Swaleside Prison: Video shows inmates' riot
This video has been removed for rights reasons.
Part of a prison wing that was taken over by about 60 inmates has been reclaimed, the Prison Service has said.
Specialist "Tornado" teams were sent into HMP Swaleside, on the Isle of Sheppey, Kent, after a disturbance at about 19:00 GMT on Thursday.
This video shows inmates brandishing snooker balls and setting off fire extinguishers, as Peter Whittlesea reports from outside the jail.
