Prison inspectors have praised staff at a jail in Sussex for making major improvements after riots in 2011.
Officers found that the relationship between detainees and guards at Ford open prison has greatly improved. However they also found some single cells used for two prisoners were too small.
The jail holds 500 male inmates. Publishing the report of an announced inspection of the open prison, Nick Hardwick - the Chief Inspector of Prisons said:
"Managers and staff at Ford are to be congratulated on turning round the prison after deep-seated concerns were exposed by a serious disturbance.
"This is still work in progress but HMP Ford now compares well with other open prisons. Overall, it provides a safe and decent environment, where prisoners are kept busy with good quality activity.
"Work to help prisoners resettle successfully after they are released and reduce the risk that they will reoffend has also improved, but these remain the areas where most still requires to be done."
