An inmate who climbed onto the roof of Chelmsford prison has come down after a stand-off which lasted more than 24 hours.
The Ministry of Justice has confirmed the situation has reached a peaceful conclusion.
Essex Police were called at 11am yesterday (June 12) to assist the prison service and they closed nearby roads "as a precaution".
A topless man wearing grey jogging bottoms was reported to be on the wall "shouting and throwing things".
Police formed a cordon along Sandford Road.
In December, a damning report by the Independent Monitoring Board described HMP Chelmsford as a "warehouse for prisoners" and criticised high levels of violence, bullying and staff shortages.
