However, the use of police cells as a place of safety for all persons detained under section 136 of the Mental Health Act 1983 has more than halved since 2011/12 (when figures were first collated) as shown in the following table. A joint inspection by Her Majesty’s Inspectorate of Constabulary (HMIC); Her Majesty’s Inspectorate of Prisons (HMIP); the Care Quality Commission (CQC); and Healthcare Inspectorate Wales (HIW) (published in 2013) found that the average time that each such person spent in police custody was 10 hours 32 minutes.
The Government intends to make provision in the Policing and Crime Bill, to be introduced in Parliament soon, to prohibit the use of police cells as places of safety for people under the age of 18, and to further limit their use in the case of adults. The maximum period for which a person may be detained pending a mental health assessment will also be reduced.
