The authorities are continuing to investigate after a late night riot caused the temporary closure of a wing at HMP High Down prison.

The incident is believed to have started at the prison, in High Down Lane, Sutton, sometime late on Thursday, July 23, before being successfully quashed in the early hours of the following day.

Conditions at the prison have been under scrutiny since prisoners staged a 'mackerel and dumpling mutiny' in October 2013 with the prison governor being called to the witness stand during the trial.

It is unknown precisely what caused the latest problem, or how many prisoners were involved.

A prison service spokesperson said: "A disturbance involving a number of prisoners on one wing at HMP High Down was successfully resolved at 12.45am on Friday July 24.

"There were no injuries to staff or prisoners.

"Police are investigating and appropriate action will be taken against any prisoner involved."

High Down was opened on the site of the former Banstead mental hospital in 1992 and currently operates as a Category B (non maximum security) prison for over 1,000 adult men.
