INCIDENTS of self-harm, assaults on staff and serious assaults at Huntercombe Prison have increased.
In 2015 there were 93 incidents of self-harm at the Nuffield prison compared with 63 the previous year, according to figures released by the Ministry of Justice.
This was a rise of 32 per cent and the third highest number of such incidents annually since 2004.
Assaults on staff more than trebled from seven attacks in 2014 to 22 in 2015.
Serious assaults rose from three in 2014 to eight in 2015.
Assaults by prisoners on other inmates went down slightly from 44 in 2014 to 42 in 2015 but serious prisoner-on-prisoner attacks increased from three to six across the two years.
Huntercombe has six residential units that hold 430 category C inmates from other countries.
Last month, the chief inspector of prisons warned that jails in England and Wales had become “unacceptably violent and dangerous places”.
In his first annual report, Peter Clarke said the “grim situation” revealed in the previous year’s report was now “even worse” in some areas.
New Justice Secretary Liz Truss has said she is under “no illusions” about the scale of the challenge to bring reform.
Huntercombe opened as a prison in 1946. The site was originally built as an internment camp during the Second World War.
It was a young offenders institute until 2010, when it became an adult male prison. It switched to housing exclusively foreign nationals two years later.
