KEY ANSWER

The position in brief

Usually up to 24 hours from arrival at the police station before you must be charged or released. For an indictable offence a superintendent can extend that to 36 hours, and magistrates can authorise further detention up to an absolute maximum of 96 hours. Terrorism cases have separate rules allowing up to 14 days. Your detention must be reviewed regularly, and you or your solicitor can make representations at every review.

Legal issues

When the clock starts

The 24 hours usually runs from arrival at the first police station after arrest (the "relevant time", PACE section 41(2)), or from the moment of arrest if you were arrested at the station after attending voluntarily. Different starting points apply in some cases, such as arrest in another police area.

Reviews

An inspector not involved in the investigation must review detention no later than 6 hours after it was first authorised, then at intervals of no more than 9 hours (PACE section 40). Continued detention must be necessary, for example to obtain evidence by questioning.

Extensions

  • Up to 36 hours: a superintendent, for an indictable offence, where detention is necessary and the investigation is being conducted diligently and expeditiously (section 42).
  • Beyond 36 hours: only by warrant of further detention from magistrates, at a hearing where you are entitled to be legally represented (sections 43 and 44). The total cannot exceed 96 hours.

Evidence that matters

Every review, extension and the reasons given are recorded in the custody record. Times matter: check them. See obtaining and checking your custody record.

Reasonable lines of enquiry

What a solicitor argues at a review

  • Whether further detention is truly necessary, or the police are simply waiting.
  • Whether the investigation is being progressed diligently.
  • Whether release on bail or under investigation would meet the police's concerns.

What happens next

By the end of the permitted time you must be charged, released on bail, released under investigation, or released with no further action. See released under investigation or police bail.

Immediate steps

  • Ask for a solicitor so someone can make representations at reviews.
  • Tell the custody officer about any medical needs, which can affect how long you are held.
  • Ask when your next review is due.

What should you send us?

Tell us who is held, at which police station, and roughly when they were arrested.

FREQUENTLY ASKED QUESTIONS

Questions before your next step

Can the police keep me overnight?

Yes, if it is within the time limits and necessary. You are entitled to at least 8 hours' continuous rest in any 24 hours, normally at night.

Does the clock stop while I wait for a solicitor?

Generally no. The detention clock keeps running while you wait. The main exception is time spent in hospital, or travelling there, when you are not being questioned.

Can I be arrested again after release?

If you were released because the time limit ran out, you cannot be re-arrested without a warrant for the same offence unless new evidence has come to light since your release (PACE section 41(9)).
