We are taking urgent action to make prisons safer. Assaults on our hard-working staff will never be tolerated. Prisoners should expect to face sanctions and, for serious assaults, be investigated by the police. We have invested in 5,600 body-worn cameras to help protect our prison staff, and we are working with the police and Crown Prosecution Service to prosecute prisoners who assault our staff. We are also supporting the Honourable Member for Rhondda’s Assaults on Emergency Workers (Offences) Bill, which will double the maximum sentence for an assault on an emergency worker, including prison officers.
Data about assaults by prisoners, including those on prison staff, is published in the quarterly Safety in Custody statistics. The figures for January to March 2018 are scheduled to be published on 26 July 2018. The most recent statistics were published on 26 April and cover assaults to December 2017 and can be viewed here: https://www.gov.uk/government/collections/safety-in-custody-statistics
Information as to whether assaults on prison staff result in a prosecution, conviction and sentence is not collated centrally. The information requested could only be obtained at disproportionate cost.
