asked Her Majesty's Government:

How many successful prosecutions were brought by the Crown Prosecution Service in each of the past 10 years against individuals for crimes committed while detained or sectioned under the Mental Health Act 1983.[HL8041]

Data on the number of prosecutions for crimes committed while detained or sectioned under the Mental Health Act 1983 is not centrally held by the Office for Criminal Justice Reform.
