The number of cases of self-harm at HMP Nottingham has reached a record high.
In 2017, there were more than 603 cases of self-harm at the category-B prison.
This was a rise of 21 percent from the year before, and almost double what it was in 2014, just three years earlier.
Back in 2010, there were just 177 incidents at the prison.
The Ministry of Justice, which released the figures, said it knows the numbers are ‘too high’, and that action is being taken to improve the situation.
Self-harm is so widespread at HMP Nottingham that there are 63 cases per 100 prisoners.
As recently as 2014 there were only 304 cases reported, about half last year’s total.
The total has grown every year since then to reach last year’s record high.
Last year prisoners hurt themselves seriously enough to have to go to hospital 40 times at the facility.
A spokeswoman for the Ministry of Justice said: “Prisons should be places of safety and reform, and we have been clear the number of self-inflicted deaths and self-harm is too high.
“We are rolling out new training for staff on suicide and self-harm prevention – and this has now reached more than 14,000 staff.
“We know the early days in prison are the hardest and we have been working to improve support for prisoners in their early days and weeks.
“We already provide individual support for over 2,500 prisoners identified as being at risk of self-harm or suicide every day through the assessment, care in custody and teamwork case management system.”
