Riot squads were called to a South Yorkshire jail every six weeks on average during a year of unrest, it was revealed last night.
HMP Lindholme in Doncaster was the second worst prison in the country in a league table of incidents where officers from the National Tactical Response Group were sent in to break up trouble.
During 2013 they were called to Lindholme nine times and HMP Moorland and Young Offenders’ Institution five times, with the privately-run HMP Doncaster having three riot incidents.
Shadow Justice Secretary Sadiq Khan blamed the Government for cutting prison workers while jails become more overcrowded, creating rising fears of attacks on staff.
At the start of the month the prison population stood at 85,469, with just 441 spaces left in the whole system.
One of the worst prison riots in Britain occurred at Moorland in November 2010 when £600,000 worth of damage was caused.
