Key Facts on Section 136 Detention
Straightforward breakdowns of the most searched elements regarding police mental health powers.
Is Section 136 an arrest?
Section 136 is not an arrest for a crime. You are not a criminal suspect, you will not receive a criminal record, and the police will not read you a standard PACE caution or conduct a formal tape-recorded interview.
However, it is a complete deprivation of liberty under the law. You are legally detained and cannot walk away. If you try to leave, police officers are authorized to use force to keep you in custody. Its purpose is entirely safeguarding and medical protection rather than prosecution.
Can police use Section 136 at home?
No. The police have no legal power to use Section 136 inside a private house, flat, hotel room, or a private garden. The power is strictly confined to public areas and places to which the public have access.
If the police need to enter your home to detain you for your safety, they must obtain a Section 135(1) warrant from a Magistrates' Court, which must be executed alongside a doctor and an Approved Mental Health Professional (AMHP). The only exception is if there is an immediate threat to life under Section 17 of PACE.
How long can police detain you?
The statutory limit is 24 hours. This period starts the moment you arrive at the first Place of Safety (such as the hospital clinical suite). It does not start when you are first stopped in public.
Under Section 41-style rules, a doctor can authorize an extension of up to 12 hours (total 36 hours) only if a physical medical emergency prevents the mental health assessment from being completed. High hospital demand or bed shortages do not justify an extension, and you must be released once the clock expires.
Does Section 136 show on DBS checks?
Because it is a health-related protective detention, Section 136 never appears on Basic or Standard DBS checks. It is not an arrest for a criminal offence and results in no cautions, warnings, or convictions.
However, it may be disclosed on an Enhanced DBS check if the police force's Chief Officer believes it is directly relevant to the safety of others in the specific job you have applied for (such as working in schools, care homes, or healthcare).
What happens after detention?
Once your joint assessment by a Section 12 Approved Doctor and an AMHP is complete, one of three decisions is made:
- Unconditional Discharge: You are free to leave the hospital immediately with community support recommendations.
- Voluntary Admission: You agree to stay as an informal patient to receive voluntary treatment.
- Involuntary Detention (Sectioning): You are formally detained under Section 2 (assessment up to 28 days) or Section 3 (treatment up to 6 months) if clinical criteria are met.
Procedural Timeline
Section 136 Step-by-Step Timeline
A visual breakdown of the operational sequence from the initial stop to the final outcome.
Street Stop & Care
The police officer detains the person in a public place. They explain the reasons in plain language and read the statutory warning.
Ambulance Transfer
An ambulance is requested to transport the individual as a clinical patient. Police transport is only used in extreme emergency.
Hospital HBPoS Admission
The 24-hour detention clock officially begins the moment you cross the threshold of the hospital's clinical suite.
Psychiatric Evaluation
You are assessed by a Section 12 Approved Doctor and an Approved Mental Health Professional (AMHP) to evaluate your support needs.
Discharge or Sectioning
The assessment concludes. You are either unconditionally discharged, admit yourself voluntarily, or are formally sectioned under Section 2 or 3.

Legal Threshold
What Police Officers Must Prove
The four statutory pillars required to make a Section 136 detention lawful.
Appears Mentally Disordered
The officer must observe behavior suggesting a mental disorder under Section 1 of the MHA (severe distress, hallucinations, psychosis).
Immediate Care / Control
Detention must be immediately necessary to prevent self-harm, suicide, or serious violence toward members of the public.
Public Place Requirement
The power is strictly restricted to streets, parks, public transport, or buildings. It is completely unlawful inside private homes.
Necessity & Proportionality
The officer must show that detaining the person was the least restrictive option available and that they consulted a healthcare professional if possible.
Procedural Errors
Common Mistakes Made by Police
If officers commit these errors during detention, it may render the entire action unlawful, leading to lawsuits.
Using S136 Inside a Dwelling
Arresting or detaining someone inside a private home, hallway, or garden without a warrant under Section 135(1) constitutes illegal trespass.
Over-Detention
Holding a patient past the 24-hour mark without a valid, senior doctor-authorized medical extension constitutes false imprisonment.
Unnecessary Force & Handcuffing
Applying handcuffs to a compliant person in distress without clear clinical justification or writing it in logs breaches use of force rules.
Police Station Misuse
Detaining a child in a police cell (strictly illegal) or placing an adult in custody without meeting the extreme risk criteria.
Poor BWV Recording
Failing to record the initial detention, handcuffs application, or warning procedures on Body-Worn Video undermines force transparency.
Can Police Use Section 136 At Home?
A critical limitation of Section 136 is its geographic restriction. Police officers cannot detain a person under Section 136 in a private dwelling or any area associated with a private dwelling (such as a private garden, communal hallways of a locked block of flats, or private driveways).
If an individual is in mental health crisis inside their house, police officers must secure a Section 135(1) warrant from a Magistrates' Court. This warrant authorizes police to enter the home—by force if necessary—alongside an Approved Mental Health Professional (AMHP) and a doctor to safely remove the person to a Place of Safety.
If the police enter your home without a Section 135 warrant or without utilizing their life-and-limb entry power under Section 17 PACE to detain you under Section 136, it is an illegal entry and constitutes a trespass and false imprisonment.
Does Section 136 Show On DBS Checks?
Because Section 136 is a protective, medical safeguarding power rather than a criminal process, it does not create a criminal record. It will not result in a conviction, caution, reprimand, or warning.
Consequently, Section 136 detentions never appear on Basic or Standard DBS checks.
However, there is a possibility it may be disclosed on an Enhanced DBS check. Under the Police Act 1997, a Chief Officer can disclose non-conviction details (referred to as "approved information") if they believe it is relevant to the specific role applied for (e.g., working with children or vulnerable adults) and ought to be disclosed. This is evaluated on a case-by-case basis under strict guidelines.
Can You Be Handcuffed Under Section 136?
Yes, police officers can legally use handcuffs or other physical restraints (such as leg restraints or limb wraps) when detaining you under Section 136. However, the use of handcuffs is never automatic.
Under Section 117 of PACE, any force used by officers must be necessary and proportionate. Officers must establish a specific, objective risk—such as active self-harm attempts, violence toward others, or a high likelihood of escape—that cannot be managed by verbal de-escalation.
Can You Refuse Medication Under Section 136?
Yes. Under Section 136, you retain the legal right to refuse psychiatric treatment and medication. This is because "Part 4" of the Mental Health Act (which governs treatment without consent) does not apply to individuals held under Section 136.
The purpose of Section 136 is purely to hold you for assessment, not to administer forced psychiatric treatment.
However, there are emergency exceptions: doctors can administer medical treatment without your consent under common law (doctrine of necessity) or under Section 62 of the Act if it is immediately required to save your life, prevent serious physical harm, or manage a severe physical medical emergency.
The Purpose of
Section 136
The conceptual foundation of Section 136 has undergone a radical transformation since the inception of the Mental Health Act in 1983. Historically, the interaction between the police and those in mental health crisis was often viewed through a prism of public order management. However, in 2026, the legislative and operational doctrine is focused entirely on protective detention and the decriminalisation of crisis.
Decriminalisation
Modern policing recognises that a mental health crisis is a medical emergency, not a criminal offence. Section 136 is the legal mechanism that bridges the gap between the street and the clinic.
Safeguarding Doctrine
The power is inherently preventative. It exists to provide immediate 'care or control' to prevent harm to the individual or others, adhering to the core police duty to protect life.
This shift in doctrine is reinforced by the Human Rights Act 1998. Specifically, any detention under Section 136 must be compatible with Article 5 (Right to liberty and security) and Article 8 (Right to respect for private and family life). For a Section 136 detention to be lawful, it must be the least restrictive option available to the officer to ensure the safety of the person in crisis.
The Legal
Threshold Test
For an officer to exercise their powers under Section 136, a specific two-stage legal test must be satisfied. Unlike a criminal arrest, which requires "reasonable grounds to suspect," Section 136 is built on the officer's subjective belief based on objective observations.
"Appears to have a mental disorder"
The officer does not need to be a medical professional. They only need to observe behavior that suggests a mental disorder (as defined by Section 1 of the MHA). This can include hallucinations, severe distress, or irrational behavior.
"Immediate need of care or control"
The need must be immediate. If the risk can be managed through voluntary referral or later intervention, Section 136 should not be used. Control is necessary to prevent self-harm or violence.
"In the person's interests or safety of others"
The detention must be a proportionate response to the risk. If the person is only a danger to themselves, the detention is still authorized if it is in their vital interests.
Important: No suspicion of a crime is required. An individual can be leading a perfectly law-abiding life, but if they are standing on a bridge in extreme distress, the legal test for Section 136 is met.
Public Place
Requirement
Historically, Section 136 could only be used in a "place to which the public have access." Following the Policing and Crime Act 2017, the definition was expanded, but it still excludes private dwellings. This distinction is the most common cause of procedural errors in mental health detention.
Where 136 Applies
- Public Highways and Pavements
- Parks and Public Squares
- Shops and Shopping Centres
- Vehicles in public areas
- Railway stations and Airports
- Essentially: Anywhere NOT a dwelling
Where 136 DOES NOT Apply
- Private Houses and Flats
- Hotel Rooms (once checked in)
- Hospital Wards
- Care Home private rooms
- Police Station custody suites
- Use Section 135(1) instead
Comparison: Section 135 vs 136
| Feature | Section 135(1) | Section 136 |
|---|---|---|
| Location | Private Dwelling | Public Place |
| Requirement | Magistrates' Warrant | Officer's Observations |
| Personnel | Police + AMHP + Doctor | Police (consultation req) |
The 24-Hour
PACE-Style Clock
A person detained under Section 136 is in the custody of the state. Therefore, strict time limits apply to ensure that medical assessment takes place without delay. In 2026, the statutory limit is 24 hours, which represents a significant reduction from the historical 72-hour power.
How long can police detain under Section 136?
Authority Threshold: 24 Hours (Max Extension 36 Hours)
The 24-hour clock starts the moment the person arrives at the first Place of Safety. If the person is detained in public at 10:00 AM but arrives at the hospital at 11:30 AM, the clock starts at 11:30 AM.
The Assessment Process
During these 24 hours, the person must be seen by a Registered Medical Practitioner (usually a section-12 approved doctor) and an Approved Mental Health Professional (AMHP). The detention only ends when the assessment is complete or the period expires.
Extension to 36 Hours
An extension of up to 12 hours (total 36) can be authorized by the assessment doctor if it is necessary to complete the assessment because of the person's physical condition or another exceptional circumstance. High demand for beds is NOT a valid legal reason for extension.
Place of Safety
Explained
A "Place of Safety" is the designated location where a person detained under Section 136 is taken for assessment. In 2026, the law is explicit: a police station is not a place of safety for a child, and its use for adults is restricted to the most extreme and exceptional circumstances.
Primary: NHS Mental Health Suite
The vast majority of Section 136 detentions result in a transfer to a dedicated Health Based Place of Safety (HBPoS). These suites are staffed by mental health nurses and provide a clinical, non-punitive environment for assessment.
Exceptional: Police Custody
Use of a police cell is now legally restricted to cases where the person's behavior poses an imminent risk of serious injury or death to themselves or others, AND that risk cannot be managed in a hospital. Even then, the use of custody must be reviewed by a senior officer immediately.
The Role of the Ambulance Service
National guidance dictates that a person detained under Section 136 should ideally be transported by ambulance, not a police vehicle. This reinforces the principle that the person is a patient, not a prisoner. Police may only transport the person if the ambulance delay is excessive and the risk of waiting outweighs the benefit of clinical transport.
Detainee Rights
& Safeguards
Detention under Section 136 is an interference with a person's fundamental right to liberty. To remain lawful, it must be accompanied by strict procedural safeguards. These rights differ significantly from those granted under PACE for criminal arrests.
Right to Medical Assessment
The primary right is to be assessed 'as soon as is reasonably practicable' by an AMHP and a Section 12 Approved Doctor. The detention cannot be extended simply because the assessors are busy.
Right to be Informed
The officer must explain the reasons for detention in simple, non-technical language. The person must be told they are NOT under arrest for a crime but are being detained for their safety.
Right to Notify
The person has the right to have one person (friend, relative, or solicitor) informed of their whereabouts. This is similar to PACE Section 56 but adapted for mental health contexts.
Access to IMHA
If the detention proceeds to a hospital section (S.2/3), the person gains a statutory right to an Independent Mental Health Advocate (IMHA) to help them understand their rights and appeal.
Appropriate Adult (AO)
If the person is under 18 or has a significant cognitive impairment, an Appropriate Adult must be present to ensure their welfare during the police-led elements of the detention.
Humane Treatment
The person must be provided with food, water, and medical care for any physical injuries. The use of handcuffs must be 'reasonable and proportionate' and recorded on Body-Worn Video.
Use of Force
Legal Framework
The use of force on a person in mental health crisis is one of the most scrutinized police actions in the UK. While Section 136 provides the power to detain, it does not automatically grant the right to use unlimited force. Officers must balance their duties under common law and statute.
This section provides the general authority to use reasonable force to exercise any power conferred by PACE or the Mental Health Act. If the detention itself is lawful, reasonable force can be used to prevent the person from leaving or harming themselves.
Officers have a common law duty to prevent a breach of the peace. If the person's crisis manifests as violence toward others, force may be justified under this duty or Section 3 of the Criminal Law Act 1967.
The Taser & Restraint Threshold
In 2026, the use of TASER on a person in crisis is a last-resort action. It must only be used where there is a threat of "serious violence" and other tactical options (like negotiation or containment) have failed. All use of force under Section 136 must be captured on Body-Worn Video (BWV). Failure to record the interaction significantly increases the risk of successful civil litigation for assault.
After Detention
Possible Outcomes
The conclusion of the 24-hour assessment period marks the end of Section 136 authority. At this point, the person must either be discharged or moved to another legal status. The police power does not "convert" into long-term detention; that is a clinical decision made by the AMHP and doctors.
1. Unconditional Discharge
The assessment concludes that the person does not have a mental disorder justifying detention, or that they can be supported safely in the community. They are free to leave immediately.
2. Voluntary Admission (Informal)
The person agrees to stay in hospital as a 'voluntary patient'. They have the same rights as a physical health patient and can technically leave at any time (subject to S.5 holding powers).
3. Section 2 Detention
The person is detained for 'assessment' for a period of up to 28 days. This is used when the doctors are not yet sure of the diagnosis or the exact treatment required.
4. Section 3 Detention
The person is detained for 'treatment' for up to 6 months (renewable). This requires a firm diagnosis and a clear treatment plan that cannot be delivered in the community.
5. Community Support (CTO)
The person is released with a Community Treatment Order or a Care Programme Approach (CPA) plan, involving regular visits from a Community Mental Health Team (CMHT).
Common
Misconceptions
Because Section 136 involves police officers and the removal of liberty, it is frequently confused with criminal arrest. In 2026, it is vital for the public and legal professionals to distinguish fact from fiction regarding mental health detention.
"Section 136 is an arrest"
Myth. While it involves detention, it is not an arrest for a crime. The person is not a "suspect," and the legal framework is provided by the Mental Health Act, not the criminal sections of PACE.
"It creates a criminal record"
Myth. Section 136 detention does not appear on a standard criminal record check. It may appear on an Enhanced DBS check if the police deem it "relevant" to a specific role, but it is not a conviction or caution.
"Police decide how long you stay"
Myth. The police only provide the initial "care and control." Once at a Place of Safety, the clinical assessment (and any subsequent hospital section) is entirely the responsibility of medical professionals and AMHPs.
"Police can 136 you in your garden"
Myth. If the garden is part of a private dwelling (and not accessible to the public), Section 136 does not apply. In 2026, officers must have a Section 135 warrant to detain someone on private residential property.
Interaction with
Arrest Powers
A complex legal situation arises when a person in mental health crisis is also suspected of committing a criminal offence. Officers must decide which legal power takes precedence: the need for medical assessment (S.136) or the need for criminal investigation (S.24 PACE).
The "Divergent" Path
The Home Office guidance is clear: Health should take priority over prosecution where the offence is minor and the crisis is severe. If a person commits a low-level "Section 5 Public Order" offence while in crisis, they should be detained under Section 136. However, for serious indictable offences (like GBH or Robbery), an arrest under Section 24 PACE is often required to ensure evidence preservation, though the person must still receive immediate psychiatric care in custody.
Can a 136 detention "turn into" an arrest?
Yes. If a person is detained under Section 136 but then commits a serious assault on hospital staff or police, the officer can "convert" the status by arresting the person for the fresh offence. Conversely, a person arrested for a crime can be de-arrested and immediately detained under Section 136 if their mental state is found to be the primary concern.
Civil Claims &
Safeguards
As an "Institutional Authority," it is important to note that the misuse of Section 136 is a grounds for significant civil litigation against a Chief Constable. Because the power is so broad, the courts demand literal adherence to the statutory requirements.
Wrongful Detention
If the person was NOT in a public place, or if the officer had no evidence of a potential mental disorder, the detention is "void ab initio." This leads to a claim for false imprisonment.
Article 5 Violation
Under the Human Rights Act, detention must be "lawful" and not "arbitrary." A detention that exceeds the 24-hour limit without valid medical extension is a breach of Article 5.
Tort of Battery
If the use of force (Chapter 7) was disproportionate or was applied after the legal authority for detention had expired, it constitutes a criminal assault and a civil battery.
