Question to the Ministry of Justice:

To ask the Secretary of State for Justice, in the last 12 months, how many individuals convicted of (a) a violent offence and (b) homicide had a recorded history of detention under the Mental Health Act 1983.

The Ministry of Justice does not hold the information requested. While the Ministry of Justice holds data on convictions, our data relating to the Mental Health Act 1983 covers only individuals detained as restricted [Criminal Justice] patients and does not capture any prior detention under the Act.

NHS England is responsible for information relating to detentions under the Mental Health Act 1983. Any relevant information is therefore held separately by different Departments and is not linked.

As a result, we are unable to provide a breakdown of individuals convicted of violent offences or homicide who have a prior history of Mental Health Act detention.
