The percentage of black or minority ethnic background (BME) detainees in the UK’s young offender institutions is the highest on record, accounting for more than half of all boys held, a watchdog report shows. The figures have been recorded since the HM Inspectorate of Prisons began carrying out the analysis in 2001. The BME figure increased to 51 per cent in 2017-18 from 48 per cent the previous year. Researchers found that the proportion of boys who identified as being from a black or minority ethnic background varied depending on the establishment, from one in five (21 per cent) at the Keppel Unit in West Yorkshire, to nearly three quarters (71 per cent) at Feltham, in Hounslow, south-west London. The figures are detailed in a study on the perceptions of those aged between 12 and 18 who were held in YOIs or secure training centres (STCs) in England and Wales from April 2017 to March 2018.
