Prison officers at Feltham used force to control violent young prisoners more often than anywhere else in the country last year.
Records from the Ministry of Justice revealed staff had to physically restrain inmates on 1,574 occasions at the young offenders institute (YOI) on Bedfont Road, Feltham, in 2014.
This means on average staff at the prison used force to control prisoners or to defend themselves against being attacked, more than four times a day, twice as much as anywhere else in the UK.
However, the total was lower than in 2013 when there were more than 2,000 uses of force at the west London young offenders institution.
Prisons minister Andrew Selous said: “Staff only use restraint as a last resort to prevent violence, and where no other means of controlling the prisoner is possible.” He added that health professionals examine every prisoner who is physically restrained by staff.
The second highest recorded use of physical force by prison officers was at Hindley YOI in Wigan, Manchester, where it was used 773 times, followed by Cookham Wood YOI in Kent.
At YOIs across England and Wales, officers resorted to use force more than 9,000 times last year, of which 10 YOIs were responsible for around 70% of forcible restraint around the country.
