HC Deb 19 July 1923 vol 166 c2475
28. Sir ROBERT NEWMAN

asked the Home Secretary how many persons during the last four years have become insane and been certified as such while undergoing terms of imprisonment; whether any of them have died in that condition before being released from custody; and how many convicted persons during the last four years have committed suicide while serving a sentence of imprisonment?

Mr. BRIDGEMAN

The number of convicted, debtor and surety prisoners certified insane in prison during the last four years is 432. None of these persons died while still in prison and before removal to an asylum. I have no information as to how many of these persons died before they were discharged from asylums. During the same four years 28 prisoners committed suicide in prison.
