Police detention rights: the protections that apply from the moment you arrive
SavePolice detention rights are the legal protections you hold while in custody at a police station. You have the right to free legal advice, the right to remain silent, and the right to have someone informed of your arrest. HS Criminal Law sets out what you can and cannot be required to do, what happens during custody, and the steps you can take to protect your position.
The rights you hold in police custody
Three rights apply from the moment you arrive at the station. You have the right to consult a solicitor privately at any time, the right to have someone told you have been arrested, and the right to see the codes of practice that govern your treatment. Police must inform you of these rights when you reach the station.
The right to legal advice means a duty solicitor will be called for you if you do not know a solicitor yourself. This advice is free whether you are charged or not. You may speak to the solicitor by phone or in person before any interview, and they can sit with you during questioning.
The right to inform someone includes a friend, relative or anyone else you reasonably need to tell. Police may delay this right if they believe it will interfere with evidence or alert other suspects, but such delays are rare and must be authorised by a senior officer.
Medical care and special needs
You have the right to medical help while detained. If you feel unwell, are injured, or need medication, tell the custody officer. A healthcare professional will assess you. You also have the right to an appropriate adult if you are under eighteen or vulnerable, and to an interpreter if English is not your first language.
What you must provide to police
Certain details must be given during detention. You must provide your name, address, date of birth and nationality when asked by the custody officer. Refusing to give these details or giving false information is itself an offence.
You may be required to provide fingerprints, photographs and a DNA sample. Police have the power to take these without your consent if you have been arrested for a recordable offence. Reasonable force may be used if you refuse. Non-intimate samples such as mouth swabs do not require your permission in these circumstances.
If you are suspected of certain offences, you may be asked to provide an intimate sample such as blood or urine. This requires your written consent and, in most cases, authorisation from a senior officer. Refusal may be mentioned in court if your case goes to trial.
The right to silence and its limits
You do not have to answer questions put to you in interview. This is sometimes called the right to silence, though police will caution you that it may harm your defence if you fail to mention something you later rely on in court. That caution is a warning, not a requirement to speak.
Many solicitors advise giving a prepared statement rather than answering questions. A prepared statement sets out your account in writing without the need to respond to questioning. You can also choose to answer some questions and decline others, though doing so may be noted.
| Approach | What it involves | Risk to consider |
|---|---|---|
| Full interview | Answering police questions on record | Inconsistencies may weaken your case later |
| No comment | Declining to answer any question | Court may draw inferences if you rely on facts not mentioned |
| Prepared statement | Providing a written account, then declining questions | Statement cannot be changed once given |
| Selective answers | Responding to some questions, not others | Pattern of refusal may be noted in court |
When silence cannot protect you
Certain situations require you to provide information. If you are driving or were driving a vehicle, you must give details of who was behind the wheel when asked. Failing to do so is an offence. Similarly, breath and drug-wipe tests at the roadside or in custody are mandatory if requested.
Custody time limits and detention reviews
Police can hold you for up to twenty-four hours before they must charge or release you. This period starts when you arrive at the station. For serious arrestable offences, a superintendent may authorise detention for up to thirty-six hours, and magistrates may extend it further to a maximum of ninety-six hours.
Your detention must be reviewed at fixed intervals. The first review happens within six hours of your arrival, then every nine hours after that. The custody officer or a more senior officer conducts the review and must be satisfied that continued detention is necessary. You or your solicitor can make representations at each review.
If police do not have enough evidence to charge you by the end of the custody time limit, they must release you. You may be released on bail or released without bail while investigations continue. Further reading on what happens after charge can be found at Crown Court trial procedure: the stages from jury selection to verdict.
Treatment and conditions in custody
The custody officer is responsible for your welfare. You should be given meals at normal times, access to a toilet and washing facilities, and at least eight hours' rest in any twenty-four-hour period if detention continues overnight. Cells must be adequately heated, cleaned and lit.
You may be searched when you arrive and your property removed for safekeeping. An officer of the same sex conducts the search. Strip searches require authorisation and must be carried out by an officer of your sex, out of sight of anyone whose presence is not necessary.
You have the right to see a written record of your time in custody. This is called the custody record and includes your arrival time, when you were told of your rights, when reviews took place, and when you were interviewed or released. Ask to see it before you leave the station.
Steps to take if you are detained
- Ask for a solicitor immediately. Use the duty solicitor if you do not have your own. Do not agree to be interviewed without legal advice present.
- Tell the custody officer if you need medical help, medication or have a condition that affects your understanding. This must be recorded.
- Write down or ask your solicitor to note the time of key events – when you arrived, when rights were explained, when you were interviewed.
- Ask to see the custody record before you leave. Check it reflects what happened while you were held.
- Do not sign anything you have not read or do not understand. Your solicitor can explain documents before you sign them.
When detention is unlawful
Detention becomes unlawful if time limits are exceeded without proper authorisation, if you are held without being told why, or if your rights are denied without lawful reason. If you believe your detention was unlawful, raise this with your solicitor. It may form the basis of a challenge or complaint later. For more on raising issues after proceedings, see Sentence Appeal: Three Grounds and the Process That Follows.
The role of the custody officer
The custody officer is usually a sergeant. Their job is to authorise your detention, ensure you are told of your rights, and review whether continued detention is justified. They are independent of the investigation and may refuse to authorise detention if they believe there is insufficient evidence.
You can make requests to the custody officer for phone calls, reading material, or to speak to your solicitor again. Some requests will be granted, others refused depending on the circumstances. Refusals should be explained and noted on your custody record.
Interviews and how they are recorded
Interviews must be recorded, usually by audio or video. You should be given breaks for meals and rest if questioning continues for a long period. Your solicitor can ask for breaks, ask for questions to be rephrased, or advise you not to answer.
Police must caution you before any interview begins. The caution warns that you do not have to say anything, but that it may harm your defence if you fail to mention something you later rely on, and that anything you do say may be given in evidence. If the caution is not given, anything said in that interview may be challenged in court.
At the end of the interview, you will usually be asked to sign the record or confirm it is accurate. You can add comments if you believe something was misrepresented. Your solicitor can help you decide whether to sign. Related procedures at the police station are explained in Stop and Search: The Powers Police Hold and Four Rights You Keep.
Special warnings and adverse inference
In some cases, police give a special warning. This happens when they want you to account for an object, mark or substance found on you, or to explain why you were in a particular place. If you fail to account for it and later rely on an explanation in court, a jury may draw an adverse inference. Your solicitor will tell you if a special warning is given and what it means.
What happens after detention ends
Detention ends in one of several ways. You may be charged and bailed to appear at court, charged and kept in custody to appear the next day, released under investigation while enquiries continue, or released with no further action. Each outcome depends on the evidence police have gathered and the seriousness of the suspected offence.
If you are bailed, you may have conditions attached such as residing at a particular address, reporting to a police station at set times, or not contacting certain people. Breaching bail conditions can lead to arrest and further detention. The implications of not following court requirements are covered at Court order breach: consequences, penalties and three actions to take.
Being released under investigation means police can continue to gather evidence without setting a bail date. There is no time limit for this stage, though the investigation should progress without unnecessary delay. You remain under investigation until you are told otherwise.
