Arrest, Search
and Seizure

Powers of arrest, stop and search and entry, search and seizure are Blackstone's Police Manual chapters 3.3, 3.1 and 3.2 in the 2026 edition. This page sets out the law with section numbers, the ranks and what must be said, then the traps, then six worked practice questions.

Short answer: what trips candidates up on arrest, stop and search, and entry and seizure?

Mostly small words and small ranks. Suspect or believe. Inspector, superintendent or no authority at all. Twenty-four hours, three months or one month. And what must be said: under s.28 PACE the person must be told they are under arrest and the ground, even where the ground is obvious. Learn each power as a short card: who, threshold, rank, time limit, what must be said, what is recorded.

Arrest by a constable: section 24 PACE

A constable may arrest without a warrant for any offence, but only if two things are true. Code G para 2.1 puts it plainly: a lawful arrest requires a person's involvement or suspected involvement in an offence and reasonable grounds for believing that the arrest is necessary. It can never be necessary to arrest a person unless there are reasonable grounds to suspect them of an offence.

Limb one: the offence

Section 24(1) to (3): who can be arrested
SituationSectionThreshold
to be about to commit, or in the act of committings.24(1)(a) and (b)No grounds test: the person actually is
reasonably suspected to be about to commit, or committings.24(1)(c) and (d)Reasonable grounds for suspecting
offence suspected to have been committed, person suspected of its.24(2)Reasonable grounds for suspecting the offence and the person
offence has been committed, person guilty or suspected of its.24(3)Guilty, or reasonable grounds for suspecting guilt

The suspicion must be reasonable and objective. Code G para 2.3A requires some reasonable, objective grounds based on known facts and information relevant to the likelihood that the offence has been committed and that the person committed it. Note 2A reminds officers that facts which point to innocence, such as a self-defence account, may dispel suspicion.

Limb two: necessity (s.24(4) and (5))

The power is exercisable only if the constable has reasonable grounds for believing that, for one of the reasons in s.24(5), arrest is necessary. Code G para 2.7 says the criteria are exhaustive. The officer must be satisfied at least one applies (para 2.5), and deciding whether to arrest, grant street bail after arrest, report for summons, issue a penalty notice or take other action remains an operational decision (para 2.4).

The statutory necessity reasons (s.24(5))
ReasonSectionNotes from the Act and Code G
Name cannot be ascertained or is doubteds.24(5)(a)The constable does not know and cannot readily ascertain the name, or has reasonable grounds to doubt a name given (Code G para 2.9(a): hesitation can ground doubt; consider mobile fingerprinting where available)
Addresss.24(5)(b)Correspondingly for the address; for summons purposes an address must be one where the person will be long enough to be served (Code G para 2.9(b))
Prevent injury, injury to self or otherss.24(5)(c)(i) and (ii)Causing physical injury to themselves or another, or suffering physical injury
Prevent loss or damage to propertys.24(5)(c)(iii)Code G gives the example of a persistent property offender likely to continue
Prevent an offence against public decencys.24(5)(c)(iv) and (6)Only where members of the public going about their normal business cannot reasonably be expected to avoid the person
Prevent unlawful obstruction of the highways.24(5)(c)(v)Code G suggests a warning first where practicable (Note 2D)
Protect a child or other vulnerable persons.24(5)(d)From the person in question
Prompt and effective investigations.24(5)(e)Wide in scope: includes the need to interview where voluntary attendance is not practicable, preserving evidence, searching premises, detention beyond 24 hours (Code G para 2.9(e))
Prevent hindrance of prosecution by disappearances.24(5)(f)Unlikely to attend court, or no satisfactory address for service
Necessity is not a last resort test

Code G Note 2C says the officer is not required to be satisfied that there is no viable alternative, but should consider arrest to be the practical, sensible and proportionate option at the time. Notes 2H and 2I add that the criteria do not permit arrest solely to take and check fingerprints, samples or photographs routinely, or solely because the offence is a drug-testing trigger offence.

Arrest is a significant interference with the right to liberty under Article 5 ECHR (Code G para 1.2). For the human-rights and use-of-force side, see our use of force and human rights revision page.

Citizens' arrest: section 24A PACE

A person other than a constable may arrest without warrant under s.24A, but the power is much narrower than a constable's. The table compares the two.

Constable (s.24) against citizen (s.24A)
FeatureConstable, s.24Citizen, s.24A
OffencesAny offenceIndictable offences only (includes either-way). Not Public Order Act 1986 Part 3 or 3A
Offence statusSuspected is enough for (1) to (3) as listeds.24A(1): in the act, or reasonable grounds for suspecting in the act. s.24A(2): applies only where an indictable offence has been committed
Necessity reasonsSix groups in s.24(5)Four only: injury to self or others, suffering injury, loss or damage to property, making off before a constable can assume responsibility
Name and addressA reason to arrestNot a reason available to a citizen
Constable available?Not relevantMust appear not reasonably practicable for a constable to make the arrest instead (s.24A(3)(b))

Two points are easy to miss. First, s.24A(2) only applies where an indictable offence has been committed: someone who arrests a person they believe is guilty of an offence that turns out never to have happened cannot rely on that limb. Second, a constable who takes over a citizen's arrest must take the person to a police station as soon as practicable under s.30(1)(b) and (1A), and the s.28 information duties still apply.

What must be said on arrest: section 28 and Code G

Section 28 is short and heavily examined. An arrest is not lawful unless the person is informed that they are under arrest as soon as practicable (s.28(1)), and not lawful unless they are informed of the ground for the arrest at the time or as soon as practicable afterwards (s.28(3)). For a constable, both duties apply regardless of whether the fact or the ground is obvious (s.28(2) and (4)). The only statutory exception is s.28(5): it was not reasonably practicable to inform the person because they escaped from arrest before the information could be given.

Code G adds more than the statute. The arrested person must be told they are arrested and the relevant circumstances in relation to both limbs, which means the suspected offence and the reason arrest is necessary (paras 2.2, 2.9, 3.3, Note 3). The custody officer must be told these matters on arrival. A caution must be given on arrest unless impracticable by reason of the person's condition or behaviour, or already given immediately before arrest (para 3.4), in these terms (para 3.5):

"You do not have to say anything. But it may harm your defence if you do not mention when questioned something which you later rely on in Court. Anything you do say may be given in evidence."

Minor deviations from the words are not a breach if the sense is preserved (para 3.6). The arresting officer must record the nature and circumstances of the offence, the reason or reasons arrest was necessary, the caution and anything the person said (para 4.1). When explaining why a criterion applies, it is not necessary to disclose details that might undermine the investigation (Note 3).

Detention and questioning after arrest are on our PACE Code C revision page.

Voluntary attendance, taking to the station and street bail

Not every suspect needs to be arrested to be interviewed. Code G Note 2F requires an officer who believes an interview is necessary to consider whether voluntary attendance is a practicable alternative. If it is, arrest is not necessary for that purpose. When arranging attendance, the officer should explain that arrest will become necessary if the person does not agree to attend at a suitable time, fails to attend, or fails to remain for the interview to be completed.

Voluntary attendance and what follows arrest elsewhere than at a station
PointAuthorityRule
Voluntary attendances.29Entitled to leave at will unless arrested; informed at once if prevented from leaving
Arrest on arrival for a voluntary interviewCode G Note 2GOnly if new information after the arrangement means voluntary attendance ceased to be practicable and it was not reasonably practicable to arrest before; the possibility of leaving mid-interview is not a valid reason
Taking to a police stations.30(1A)As soon as practicable after arrest elsewhere than at a police station
Release without bail before the stations.30(7) and (7A)Must release if, before reaching the station, a constable is satisfied there are no grounds for keeping the person under arrest; record the release
Delays.30(10), (10A), (11)Allowed if the person's presence elsewhere is necessary for investigations reasonable to carry out immediately; reasons recorded when the person first arrives at the station (or is released on street bail)
Street bails.30A(1A), (3A), (3B), s.30BConstable satisfied bail is necessary and proportionate; a custody officer authorises; no surety, security or bail hostel requirement; the bail end date is three months from the day after arrest
The trap in Note 2G

An officer cannot arrest someone on arrival for a voluntary interview just because they might walk out halfway. If they do decide to leave part way through, the police can consider at that point whether arrest has become necessary. Arrest on arrival needs new information since the arrangement, and it must not have been reasonably practicable to arrest the person before they attended.

Street bail was changed by the Police, Crime, Sentencing and Courts Act 2022. As shown on legislation.gov.uk, the constable must be satisfied that bail is necessary and proportionate, a custody officer must authorise it, and the person must be required to attend at a time on the bail end date, which is the last day of the period of three months beginning with the day after the arrest (ss.30A(1A) and 30B). A constable may arrest without warrant on reasonable grounds for suspecting a street bail condition has been broken (s.30D(2A)); the person must then be taken to a police station as soon as practicable. The 2022 Act changed the street bail rules from 28 October 2022, so older revision material may describe the earlier position; check the date of anything you rely on.

Section 60 and other suspicionless powers: the authorisation traps

Section 60 Criminal Justice and Public Order Act 1994 is the most examined suspicionless power because it has ranks, times and a two-level threshold. Break it into four questions.

  1. Who can authorise? An officer of inspector rank or above who reasonably believes one of three things: that incidents involving serious violence may take place in a locality in the force area and an authorisation is expedient to prevent them; that an incident of serious violence has taken place, a dangerous instrument or offensive weapon used in it is being carried in a locality, and an authorisation is expedient to find it; or that persons are carrying dangerous instruments or offensive weapons without good reason in a locality (s.60(1)). Code A Note 11 says the belief must have an objective basis, such as intelligence or relevant information.
  2. For how long, and in what form? A specified period not exceeding 24 hours (s.60(1)); in writing, signed, specifying the grounds, locality and period (s.60(9)). Oral authorisation is permitted only for the incident-has-happened ground where writing is not practicable, and must be recorded in writing as soon as practicable (s.60(9ZA); Code A para 2.13).
  3. Who can extend and who must be told? A superintendent or above may direct that it continues for a further 24 hours if it appears expedient, having regard to offences committed or reasonably suspected to have been committed in connection with the activity authorised (s.60(3)), in writing unless that is not practicable, when it must be recorded in writing as soon as practicable afterwards (Code A para 2.14). An inspector who gives an authorisation must cause a superintendent or above to be informed as soon as practicable (s.60(3A)). Code A para 2.14C also expects the inspector to communicate the decision to the public as soon as possible where it is operationally beneficial.
  4. What can the constable do? A constable in uniform may stop any pedestrian and search them, or anything carried, for offensive weapons or dangerous instruments, and stop any vehicle and search the vehicle, driver and passengers, whether or not there are grounds for suspicion (s.60(4) and (5)). They may seize a dangerous instrument or an article they reasonably suspect to be an offensive weapon (s.60(6)). Failure to stop when required is a summary offence punishable by up to one month's imprisonment or a level 3 fine, or both (s.60(8)).
Where the 'no suspicion' sits

The searching officer needs no suspicion about the person or vehicle. The authorising officer needs a reasonable belief. An answer option that moves the suspicion test to the constable, or that lets a sergeant authorise, is wrong. The selection of people to stop should still reflect an objective assessment linked to the purpose of the authorisation (Code A para 2.14A), and the powers must not be used for reasons unconnected with it.

Other points the Code expects: the person searched or the driver of a vehicle stopped can ask within 12 months for a written statement that the stop or search was under s.60 (s.60(10), (10A); Code A para 2.14B), and the search record and the pre-search explanation must cover the nature of the power, the authorisation and the fact that it has been given (Code A paras 3.8(d)(ii) and 4.3).

Two related powers share the pattern. Section 60AA lets a constable in uniform require removal of an item worn wholly or mainly to conceal identity, and seize an item intended to be worn for that purpose, where a s.60 authorisation is in force or a separate s.60AA(3) authorisation has been given by an inspector or above for up to 24 hours. Section 11 Public Order Act 2023 gives an inspector or above a similar suspicionless authorisation, up to 24 hours, for protest-related prohibited objects where they reasonably believe the s.11(1) conditions are met and the s.11(4) necessity points apply. A superintendent or above may direct that it continues for a further period not exceeding 24 hours (s.11(5)), and an inspector who gives one must cause a superintendent or above to be informed as soon as practicable (s.12(1)).

Entry without a warrant: sections 17, 18, 32 and the common law

Section 17 lets a constable enter and search premises for specified purposes. Section 17(5) abolishes all common law powers of entry without warrant, and s.17(6) saves only the power to deal with or prevent a breach of the peace. The section creates no power of arrest (Code B para 4.1).

Section 17(1): the purposes of entry (abridged, check the Manual for the full list)
PurposeSectionNotes
Executing an arrest warrant or committal warrants.17(1)(a)Any constable
Arresting for an indictable offences.17(1)(b)Any constable; reasonable grounds for believing the person is on the premises
Arresting for listed offences, mostly summary (including some Public Order Act 1936 and 1986 offences, Criminal Law Act 1977 ss.6 to 8 and 10, Road Traffic Act 1988 ss.4 and 163, Transport and Works Act 1992 s.27, animal welfare and squatting offences)s.17(1)(c)Entry for s.17(1)(c)(ii), (iv) and (vi) offences only by a constable in uniform (s.17(3))
Arrest under s.30D(1) or (2A) or s.46A(1) or (1A) PACE; s.5B(7) or s.7(3) Bail Act 1976; s.97(1) Legal Aid, Sentencing and Punishment of Offenders Act 2012s.17(1)(cab)The bail-related arrest powers; the list is not exhaustive of s.17(1), so read the full section in the Manual
Recapturing a person unlawfully at larges.17(1)(cb) and (d)(d): any person unlawfully at large whom the constable is pursuing
Saving life or limb or preventing serious damage to propertys.17(1)(e)The only purpose where the 'reasonable grounds for believing the person is on the premises' condition does not apply (s.17(2))

Outside saving life or limb or preventing serious damage to property, the power is exercisable only if the constable has reasonable grounds for believing that the person they are seeking is on the premises, and where the premises consist of two or more separate dwellings it is limited to the common parts and any dwelling where the constable has reasonable grounds for believing the person may be (s.17(2)). The search is limited to what is reasonably required for the purpose of the entry (s.17(4)).

After arrest: section 18 against section 32

These two sections look alike and are routinely mixed in exam scenarios. The table separates them.

Section 18 against section 32(2)(b)
FeatureSection 18Section 32(2)(b)
PremisesOccupied or controlled by the arrested personWhere the person was when arrested or immediately before
Arrest forAn indictable offenceAn indictable offence (for the premises power)
ThresholdReasonable grounds for suspecting evidence is there (s.18(1))Reasonable grounds for believing evidence is there (s.32(6))
Evidence ofThe arrest offence, or another indictable offence connected with or similar to itThe arrest offence only
AuthorityInspector or above in writing, unless s.18(5) applies (then inform an inspector after)None needed
Legally privileged materialExcluded from the evidence for which you may search (s.18(1))No special rule on the face of s.32; s.19(6) bars seizure of legally privileged items in all cases
Several dwellings in one buildingNo special limit in s.18Only the dwelling where the arrest took place or the person had been, and common parts (s.32(7))
Scope of searchOnly so far as reasonably required to discover the evidence (s.18(3))Only so far as reasonably required (s.32(3))

Section 32 also allows search of the arrested person (s.32(1) if the person may present a danger to themselves or others; s.32(2)(a) for items that might assist escape or be evidence, on reasonable grounds for believing the person may have concealed such things, s.32(5)). It does not authorise removal of clothing in public beyond an outer coat, jacket or gloves, though it does authorise a search of the mouth (s.32(4)).

The section 18(5) exception

An officer may search under s.18 before the person is taken to a police station (or released on street bail), without an inspector's prior authority, if the person's presence at a place other than a police station is necessary for the effective investigation of the offence (s.18(5) and (5A)). The constable must then inform an inspector or above as soon as practicable. That officer records the grounds and the nature of the evidence sought, in the custody record if the occupier is in police detention (s.18(6) to (8)). An inspector's authority is a feature of s.18 searches, not of s.30 delay.

Code B para 4.3 repeats that inspector authority should be given only when the authorising officer is satisfied the premises are occupied or controlled by the arrested person and the necessary grounds exist, and says that where possible the authority should be recorded on the Notice of Powers and Rights.

Search warrants: section 8 PACE, sections 15 and 16, and the MDA warrant

A section 8 warrant from application to execution
StageRuleDetail
Who applies, who issuesA constable applies; a justice of the peace issues (s.8(1))Application is made ex parte and supported by a written information; the constable answers on oath (s.15(3), (4))
What the justice must be satisfied ofReasonable grounds for believing that an indictable offence has been committed, that there is material on the premises likely to be of substantial value and likely to be relevant evidence, and not legally privileged, excluded or special procedure material (s.8(1)(a) to (d))Plus one of the four conditions in s.8(3): not practicable to communicate with anyone entitled to grant entry; practicable to communicate with someone entitled to grant entry but not with anyone entitled to grant access to the evidence; entry will not be granted unless a warrant is produced; or the purpose of the search may be frustrated or seriously prejudiced unless a constable arriving can secure immediate entry
Specific premises or all premisesA specific premises warrant names the premises. An all premises warrant covers premises occupied or controlled by a named personAll premises: extra tests in s.8(1B); entry to unspecified premises needs an inspector's written authority (s.16(3A))
Number of entriesOne occasion unless the warrant says multiple (s.15(5)); multiple entries may be unlimited or capped (s.8(1D), s.15(5A))Second and later entries need an inspector's written authority (s.16(3B))
Time limitWithin three months from issue (s.16(3))At a reasonable hour unless the purpose may be frustrated (s.16(4))
On executionIf the occupier is present: identify yourself, show documentary evidence if not in uniform, produce the warrant and give a copy (s.16(5))If the occupier is absent, the same applies to another person who appears to be in charge (s.16(6))
Refused applicationA further application for the same premises needs additional grounds (Code B para 3.8)

Code B para 3.1 requires the officer to take reasonable steps to check that the information is accurate, recent and not provided maliciously or irresponsibly, and says an application may not be made on the basis of an anonymous source if corroboration has not been sought. The application must be supported by a signed written authority from an inspector or above (para 3.4(a)); in an urgent application to a justice of the peace where an inspector is not readily available, the next most senior officer on duty can give it. Superintendent authority applies instead to certain applications to a judge under the Terrorism Act 2000 and the National Security Act 2023 (para 3.4(b)).

Different statute, different clock

A justice of the peace may issue a warrant under s.23(3) Misuse of Drugs Act 1971 where there is reasonable ground for suspecting controlled drugs are in the possession of a person on premises. It authorises entry, if need be by force, and search of the premises and any persons found there, at any time or times within one month from the date of the warrant. PACE s.16(3) says three months. Code B para 6.1 says to use the shorter period if the enactment specifies one.

Entry by consent is a separate route. Code B para 5.1 requires the consent of a person entitled to grant entry, in writing on the Notice of Powers and Rights if practicable. The person must be told they need not consent, that consent can be withdrawn at any time including during the search, and that anything seized may be produced in evidence (para 5.2). Search cannot continue if consent is given under duress or withdrawn (para 5.3). In a lodging house, hostel or similar accommodation, every reasonable effort should be made to get the consent of the individual occupier, and a search should not be made solely on the landlord's consent (Note 5A).

Seizure and retention: sections 19 and 22

  • General power (s.19). A constable lawfully on any premises may seize anything if they have reasonable grounds for believing it has been obtained in consequence of an offence, or is evidence in relation to an offence they are investigating or any other offence, and it is necessary to seize it to prevent it being concealed, lost, damaged, altered or destroyed (s.19(2), (3)).
  • Computer material (s.19(4)). Electronic information accessible from the premises may be required to be produced in a form that can be taken away and read, on the same style of grounds and necessity.
  • Legal privilege (s.19(6)). No power of seizure under any enactment authorises seizing an item the constable has reasonable grounds for believing is subject to legal privilege.
  • Warrant power (s.8(2)). A constable may seize and retain anything for which a search has been authorised.
  • Retention (s.22). As long as is necessary in all the circumstances (s.22(1)), including for use as evidence at trial, forensic examination, investigation, or to establish the lawful owner (s.22(2)). Nothing may be retained for evidence or forensic examination if a photograph or copy would be sufficient (s.22(4)). Items seized because they might injure, damage property, interfere with evidence or help an escape may not be retained once the person is no longer in police detention or court custody, or is released on bail (s.22(3)).

Keep the pattern simple. Searches that need an authorisation (s.60, s.60AA, s.11 POA 2023, s.18) begin at inspector. Extensions of the suspicionless powers go to superintendent. Repeat entries and warrant applications go to an inspector. Everything else in this page is the constable's own decision, which is why those questions are really about the threshold.

Reasonable grounds against suspicion: the one-line test

Ask what the officer must be satisfied of. If it is about the offence or the item (it is there, or the person did it), the word is usually suspect. If it is about the officer's own justification for a coercive step (arrest is necessary, the person is on the premises, evidence is on the premises under s.32), the word is believe. Then check the exceptions, such as s.18 (suspecting evidence is on premises).

Six worked practice questions

These are original practice questions from our verified bank, not real or past exam questions. Each one has been checked against the primary sources; the answer is marked and the reasoning and source follow. Cover the options and answer before you scroll.

Evidence and procedure Question 1

At 3am officers find a man inside a house holding a bag of the occupier's jewellery. An officer takes hold of him and says 'You're under arrest', but says nothing about why, because the reason seems obvious. He is calm and compliant, but he is not told the ground for his arrest until he reaches the custody desk two hours later. Which statement is correct?

A. The arrest was lawful throughout, because the ground for arrest was obvious from the circumstances in which he was caught inside the house at 3am
B. The arrest was lawful, because it is enough for the custody officer to tell the suspect the grounds when he is booked in on arrival at the police station
C. The arrest was lawful, because the grounds need to be given only if he asks why he has been arrested or resists, and he was calm and compliant throughout
D. Correct: The arrest was not lawful while he was left uninformed: a constable must give the ground at the time or as soon as practicable afterwards, even if it is obvious

Section 28(3) provides that no arrest is lawful unless the person is told the ground at the time of arrest or as soon as practicable afterwards. Section 28(4) makes that apply to arrests by a constable even where the ground is obvious. The only statutory exception is in s.28(5), where it was not reasonably practicable to give the information because the person escaped before it could be given. Code G para 3.3 and Note 3 also require the person to be told why the arrest is necessary.

Evidence and procedure Question 2

A person other than a constable may arrest without warrant under s.24A PACE only if, among other things, they have reasonable grounds for believing that arrest is necessary for one of the listed reasons. Which of the following is NOT one of those reasons?

A. To prevent the person causing loss of or damage to property
B. To prevent the person making off before a constable can assume responsibility for him
C. To prevent the person suffering physical injury
D. Correct: To enable the person's name to be ascertained

The reasons available to a citizen under s.24A(4) are to prevent the person causing physical injury to himself or another, suffering physical injury, causing loss of or damage to property, or making off before a constable can assume responsibility for him. Ascertaining a name or address is a necessity reason for constables only, under s.24(5)(a) and (b). A citizen's arrest also requires that it appears not reasonably practicable for a constable to make the arrest instead (s.24A(3)(b)).

Source: PACE 1984 s.24A(3) and (4); s.24(5)

Evidence and procedure Question 3

An officer on foot patrol has no particular grounds for suspicion when she approaches a teenager in a park and asks what is in his rucksack. He politely declines to answer and carries on walking. Nothing else about his behaviour is unusual. The officer then detains him for a search under s.1 PACE, saying his refusal to answer makes her suspicious. What is the position under Code A?

A. Correct: It is unlawful: there is no power to stop or detain someone in order to find grounds for a search, and a refusal to answer questions cannot supply grounds after the event
B. It is lawful, because refusing to answer a police officer's reasonable questions about what is in a bag is in itself reasonable grounds for suspicion under Code A para 2.2
C. It is lawful, provided the officer records the refusal to answer as her grounds on the search record and offers him a copy of that record afterwards
D. It is lawful, provided a sergeant authorises the search over the radio before it starts, the reason for the authorisation is given to him, and it is noted on the search record

Code A para 2.11 states there is no power to stop or detain a person in order to find grounds for a search. Para 2.9 says reasonable grounds cannot be provided retrospectively by questioning, or by a refusal to answer questions. Note 1 confirms that, without a power to arrest or detain to search, the person is free to leave at will. If genuine grounds had come out of the conversation, the officer could have detained him at that point.

General police duties Question 4

How does a search authorised under s.60 Criminal Justice and Public Order Act 1994 differ from a standard s.1 PACE search?

A. Correct: Once properly authorised, it allows searches within a set area and time without reasonable suspicion about the particular person
B. It requires a higher standard than s.1: reasonable belief, rather than suspicion, that the specific person carries a weapon
C. It permits searches of vehicles only, never of people, and only on the public roads specified in the authorisation
D. It has no time limit once authorised, and stays in force until the authorising officer or a superintendent cancels it

Section 60 is a suspicion-independent power: once a senior officer has authorised it for a specific locality and time period (typically because of anticipated serious violence), officers can search individuals within that area without needing reasonable suspicion about that particular person, unlike s.1 PACE.

Source: s.60 Criminal Justice and Public Order Act 1994; PACE Code A

Evidence and procedure Question 5

A suspect is arrested for burglary outside his house. He says the stolen jewellery is hidden somewhere in the house and offers to show officers where. Officers decide that his presence there is necessary for the effective investigation of the offence. They search the house with him before taking him to the police station, without any prior written authority. What must happen after the search?

A. A superintendent must give retrospective written authority within 24 hours, recording the grounds and the items seized, or anything seized must be returned to the occupier
B. Nothing further is required, because s.18(5) removes the need for any involvement by a senior officer; the searching officer simply records the search and its result in their pocket notebook
C. Correct: An inspector or above must be told as soon as practicable and must record in writing the grounds and the nature of the evidence sought, in the custody record if the occupier is in police detention
D. The search was unlawful, because a s.18 search can only take place after the arrested person has been taken to a police station and an inspector has given written authority

Section 18(5) and (5A) allow a s.18 search before the person is taken to a police station, without inspector authorisation, where his presence at a place other than a police station is necessary for the effective investigation of the offence. Section 18(6) then requires the constable to inform an inspector or above as soon as practicable. Section 18(7) requires that officer to record the grounds for the search and the nature of the evidence sought. Under s.18(8), that record goes in the custody record if the occupier is in police detention.

Source: PACE 1984 s.18(1) and (4)-(8); Code B para 4.3

Evidence and procedure Question 6

A s.8 PACE warrant authorises up to three entries to a lock-up garage. Officers carried out the first entry last week. A detective sergeant now wants to enter a second time. The detective inspector who is senior investigating officer on the case says over the phone that the sergeant can go ahead. What does the law require before the second entry?

A. Nothing more. The warrant itself authorises three entries, so no further authority is needed
B. The second entry is lawful, provided the detective inspector confirms the authority in writing afterwards
C. Correct: Prior written authority from an officer of at least inspector rank who is not involved in the investigation
D. A fresh application to a justice of the peace for each later entry

Section 16(3B) provides that no premises may be entered or searched a second or later time under a multiple-entry warrant unless an inspector or above has authorised that entry in writing. Code B para 6.3A adds that this must be the prior written authority of an inspector who is not involved in the investigation. Here the SIO is involved in the investigation and only gave oral approval, so the phone call does not meet either requirement.

Edition caveat

These chapter numbers are Blackstone's 2026 edition, as listed in Appendix A of the College's 2026 candidate handbook (September 2025). We could not open the 2027 handbook's Appendix A, so we have not verified the 2027 edition numbering. If you are sitting in 2027, check the contents page of your 2027 Manuals before relying on these numbers.

We have read the chapter titles and sub-headings in the handbook, not the text of the Manuals, so the map shows where to look, not what each chapter contains in detail.

How much of the exam does this topic take?

Nobody can say in advance. The College says the subject area breakdown for a sitting is valid only for that sitting and should not be used to work out what will be tested in future. For context only, here is a count of the March 2026 sergeants' breakdown, which lists one row per scored question (140 rows). We counted the rows under three General police duties skills.

March 2026 sergeants' breakdown: rows under these three skills (one sitting only)
SkillRowsSubjects listed
Entry, search and seizure5Code B-3 Search warrants and production orders; Code B-4 Entry without warrant, particular powers; Code B-7 Seizure and retention of property; Execution of a warrant; Code B-10 Searches under Schedule 5 to the TPIM Act 2011 and Schedule 11 to the National Security Act 2023
Powers of arrest4After arrest; Arrest without warrant, citizen's arrest; Code G-3 Information to be given on arrest; Voluntary attendance at a police station or elsewhere
Stop and search3Code A-2 Types of stop and search powers (two rows); Code A-3 Conduct of searches
Total of the three skills12Of 140 scored questions. The rows shown are subject descriptions, not question wording

Three further rows under Instituting criminal proceedings (Issue of warrants once, Execution of warrants twice) sit in the Evidence and procedure area and are not counted above. Treat the table as a description of one paper, not a forecast. Powers of arrest also feed other areas: for example, the necessity reasons matter to detention, and entry powers matter to seizure and disclosure.

Worked scenarios

Illustrative examples, not real incidents, to practise applying the rules above.

1. The silent arrest An officer finds a man inside a house at 3am holding the occupier's jewellery, grabs him and says "You're under arrest". He is compliant and is told nothing else until he reaches the custody desk two hours later. The arrest was not lawful while he was left uninformed: s.28(3) and (4) require the ground at the time or as soon as practicable, even if obvious. The caution under Code G 3.4 was also due unless impracticable.
2. The shop manager A manager sees a man carrying her stock out of the shop without paying and holds him until police arrive. Theft is indictable (even low-value shoplifting counts as indictable for PACE purposes: Anti-social Behaviour, Crime and Policing Act 2014 s.176(6)), he is in the act, she has reasonable grounds for believing arrest is necessary to stop him making off before a constable can assume responsibility, and no constable is nearby. s.24A is satisfied. If he had instead been using threatening, abusive or insulting words intended to stir up racial hatred (s.18, in Part 3 of the Public Order Act 1986), s.24A(5) would remove her power.
3. The rucksack An officer with no particular suspicion approaches a teenager in a park and asks about his rucksack. He politely declines and walks on. She detains him for a search because refusing made her suspicious. There is no power to stop or detain to find grounds, and a refusal to answer cannot provide grounds retrospectively (Code A 2.9 and 2.11). She may talk to him; she may not detain him without grounds.
4. Friday night s.60 An inspector authorises s.60 for the town centre from 22:00 after a stabbing earlier that evening, signs it, and tells a superintendent soon afterwards. At 21:30 the next evening, with further knife offences reported in connection with the trouble, the superintendent extends it in writing for 24 hours. The initial authorisation was within 24 hours and informed upwards. The extension is within s.60(3), because it is expedient having regard to offences committed in connection with the activity. A constable in uniform may search without suspicion, but must explain the power, the authorisation and the fact it has been given. Section 60(3) provides for one further 24 hours, and Code A Note 12 says an extension may be given only once; any further use needs a new authorisation.
5. Burglar and house A burglary suspect is arrested outside his house. He offers to show officers where the jewellery is hidden. Officers decide his presence is necessary for the effective investigation, search with him before taking him to the station, and tell an inspector afterwards. That is s.18(5) and (5A): no prior authority, but an inspector must be informed as soon as practicable and records the grounds and the nature of the evidence sought. The search is limited to what is reasonably required.
6. Flat 4 A man is arrested for robbery inside a friend's flat in a block of ten. His home is across town. Under s.32(2)(b) officers may search Flat 4 and the common parts, such as the bin store, for evidence relating to the robbery if they have reasonable grounds for believing it is there. They cannot rely on s.32 to search his home, which would need s.18 and an inspector's authority (unless s.18(5) applies), and they cannot search the other flats.
7. The multiple-entry warrant A s.8 warrant allows up to three entries to a lock-up. After the first, a detective sergeant wants to go back and the SIO, a detective inspector, agrees by phone. s.16(3B) requires written authority from an inspector or above, and Code B 6.3A says it must be prior written authority from an inspector not involved in the investigation. The phone call is not enough.
8. Voluntary interview A suspect agreed to attend for a voluntary interview. On arrival the officer proposes to arrest him "in case he walks out". Nothing new has emerged. Code G Note 2G: arrest on arrival needs new information after the arrangement and impracticability of earlier arrest; the possibility he may leave is not a valid reason. If he later leaves, the officer can consider whether arrest is then necessary. Under s.29 he is entitled to leave at will unless arrested.

When you are ready for the next topic, the theft, robbery and burglary page covers the offences these powers are often used for, and the public order offences page covers offences such as s.4 Public Order Act 1986, which is one of the offences listed in s.17(1)(c) for entry to arrest.

What we could not verify

  • 2027 edition chapter numbers. The chapters above are the 2026 edition per the 2026 handbook Appendix A. The 2027 handbook Appendix A could not be opened. Check your own 2027 contents page.
  • What the Manuals say. We read statute and Codes on legislation.gov.uk and GOV.UK, and chapter headings in the handbook. We did not read the Blackstone's text, so how a chapter words or emphasises a point may differ. The exam tests the law as it appears in the Manuals edition for the sitting.
  • Recent amendments. The Crime and Policing Act 2026 amends parts of PACE and the CJPOA 1994 (for example, s.60(9B) was inserted on 29 June 2026). We did not review every 2026 amendment and cannot say which the 2026 or 2027 Manuals reflect. Law that changes after publication is examined only if the College gives notice.
  • Public Order Act 2023 powers. We checked ss.11 and 12 (rank, belief test, 24-hour maximum, extension, informing a superintendent). We did not check s.10 or the offences in s.11(1)(a) in detail, and the Manuals may cover them elsewhere.
  • Case law. We deliberately left out case names because we could not confirm holdings from a primary source we could open.
  • Other arrest and search powers. Mental Health Act powers, Terrorism Act powers, arrest under warrant, road check powers under s.4 PACE and drug-driving or firearms search powers are in the Manuals but not covered here. Chapter 3.3 and the sibling pages cover some of them.
  • What will be examined. The College says each subject area breakdown is valid only for its own sitting. Our count of 12 rows is a description of March 2026 only.
Quick answers

Frequently Asked Questions

What is the difference between reasonable grounds to suspect and reasonable grounds to believe?

In these chapters the statute uses both words deliberately, and the exam tests the difference. Suspicion is the lower threshold and is used for the offence (s.24(1) to (3)) and for the stop and search powers (s.1 PACE and s.23 Misuse of Drugs Act 1971). Belief is used for the necessity to arrest (s.24(4)), for the presence of the person on premises (s.17(2)(a)), and for the presence of evidence under s.32(6). Both must still be reasonable, meaning an objective basis that another person could accept (Code A para 2.2 and Code G para 2.3A).

Does a constable have to be sure that arrest is the only option?

No. Code G Note 2C says a constable need not be satisfied that there is no viable alternative to arrest, but should consider that arrest is the practical, sensible and proportionate option at the time. At least one of the six necessity reasons in s.24(5) must apply (Code G para 2.5), and it can never be necessary to arrest someone unless there are reasonable grounds to suspect them of an offence (Code G para 2.1).

Can an arrest be lawful if the person is not told why until later?

Only if the delay was as soon as practicable. Section 28(3) says no arrest is lawful unless the person is told the ground at the time or as soon as practicable afterwards, and s.28(4) says that applies to a constable even where the ground is obvious. The one statutory exception, in s.28(5), is where it was not reasonably practicable because the person escaped before the information could be given.

Can a member of the public arrest for any offence?

No. Under s.24A only for an indictable offence (which includes either-way offences), and only where the arrester has reasonable grounds for believing arrest is necessary for one of four reasons and it is not reasonably practicable for a constable to do it instead. The power does not apply to offences under Part 3 or Part 3A of the Public Order Act 1986 (s.24A(5)). Under s.24A(2) the power applies only where an indictable offence has in fact been committed.

Who can authorise a section 60 search, and for how long?

An officer of inspector rank or above, in writing, for a specified locality and a period not exceeding 24 hours (s.60(1) and (9)). A superintendent or above can extend it by a further 24 hours (s.60(3)). An inspector who gives an authorisation must cause a superintendent or above to be informed as soon as practicable (s.60(3A)). An oral authorisation is allowed only in the incident-has-happened case in s.60(1)(aa) where writing is not practicable (s.60(9ZA)).

Do officers need reasonable suspicion to search under section 60?

Not about the person or vehicle. Once an authorisation is in force, a constable in uniform may stop and search whether or not there are grounds for suspecting the person or vehicle is carrying weapons (s.60(4) and (5)). The suspicion-like threshold sits with the authorising officer, who must reasonably believe one of the conditions in s.60(1). The searching officer must still explain the power, the authorisation and the fact that it has been given (Code A para 3.8).

How long does a PACE search warrant last, and can it be used twice?

Entry and search under a PACE warrant must be within three months of issue (s.16(3)), and a warrant authorises one entry only unless it specifies multiple entries (s.15(5)). For second and later entries under a multiple-entry warrant, an inspector or above must authorise the entry in writing (s.16(3B)), and Code B para 6.3A adds that this is the prior written authority of an inspector not involved in the investigation. A Misuse of Drugs Act s.23(3) warrant is different: it lasts one month.

Which senior officer authorises a section 18 search?

An inspector or above, in writing (s.18(4)), unless the search is carried out before the arrested person is taken to a police station because their presence elsewhere is necessary for the effective investigation of the offence (s.18(5) and (5A)). In that case no prior authority is needed, but the constable must inform an inspector or above as soon as practicable (s.18(6)), and that officer records the grounds and the nature of the evidence sought (s.18(7)), in the custody record if the occupier is in police detention (s.18(8)).

What is the difference between a section 18 and a section 32 search?

Section 18 covers premises occupied or controlled by a person arrested for an indictable offence, for evidence of that offence or a connected or similar indictable offence, on reasonable grounds for suspecting it is there. Section 32(2)(b) covers premises where the person was when arrested or immediately before, for evidence relating to the arrest offence only, on reasonable grounds for believing it is there. Section 18 normally needs inspector authority in writing, and s.32 does not.

Can officers seize things that are not named in the warrant?

Yes, if another power applies. A constable lawfully on premises may seize anything on the premises under s.19(2) or (3) if they have reasonable grounds for believing it was obtained in consequence of an offence or is evidence of an offence, and it is necessary to seize it to prevent it being concealed, lost, damaged, altered or destroyed. Items the constable reasonably believes to be subject to legal privilege cannot be seized under any power (s.19(6)).

Can officers keep seized property for the whole of a trial?

Only as long as necessary in all the circumstances (s.22(1)), and not for evidence or forensic examination if a photograph or copy would be sufficient (s.22(4)). Retention of items seized because they might cause injury, damage property, interfere with evidence or help an escape ends when the person is no longer in police detention or court custody, or is on bail (s.22(3)).

Is a person who attends voluntarily for interview free to leave?

Yes. Under s.29 a person who attends voluntarily, or accompanies a constable, to help with an investigation is entitled to leave at will unless arrested, and must be informed at once that they are under arrest if a decision is taken to prevent them leaving. Code G Note 2G says that the possibility they might leave during the interview is not a valid reason to arrest them on arrival before the interview starts.

Does this page cover everything in Blackstone's chapters 3.1 to 3.3?

No. It covers the powers the exam most plausibly turns on and the traps in them. The Manuals also cover other arrest powers, arrest under warrant, terrorism-related search powers, search registers and more, and the exam tests the law only as it appears in the Manuals edition for the sitting.
