Order has been restored at the Aylesbury Young Offenders' Institution after teams of specially trained 'control and restraint' teams overpowered rioters.
The Ministry of Justice has launched an investigation into the disturbance which saw up to 100 prison officers, many in riot gear, fighting with inmates.
Police were called to the institution in Buckinghamshire at 11.46am and reports say 'substantial' damage has been caused to the workshops where the large group of inmates had barricaded themselves in.
Tom Robson, executive officer of the Prison Officers' Association, said it was a 'serious incident' and officers from other prisons had been called in to help.
The riot ended when specially-trained prison service staff intervened at 5pm.
There were no reports of any injuries to offenders or staff.
'We are happy to report that no-one has been injured in the incident and that order has been restored,' said a Thames Valley Police spokesman.
Sources said the inmates broke into the officers' mess and workshops and armed themselves with hammers, saws and chisels.
The Prison Service said it would conduct a full investigation into the circumstances of the incident. The police will also hold an investigation.
Most prisoners at Aylesbury are serving long sentences and there is a large ethnic minority population, according to a 2005 inspector's report. continues here
