Prisoners armed themselves with table legs and threw pool balls at officers during a three-day riot at a prison, a court heard.
During the “pre-planned” riot, a pool table was set on fire, furniture was thrown from landings, makeshift barricades were made with sheets tied to railings and windows and fuse boxes were smashed.
It cost £641,500 to repair the damage at Moorlands Young Offenders’ Institution near Doncaster which spread to an adult wing and left one inmate in hospital.
Dozens of prisoners had to be moved to other jails following the riot in November, 2010.
The riot only ended when officers in riot gear were called in and the prisoners surrendered, Sheffield Crown Court heard.
Three wings in House Block One were destroyed.
At the height of the trouble, prison officers fled and locked the wings behind them, effectively surrendering control of the jail.
Fifteen prisoners and ex-inmates are in the dock. Charged with rioting are Daniel Baldam, aged 23, of Berwick Hills, Middlesbrough, Christopher Wilson, 26, of Peniston Road, Doncaster, Adam Mendoza, 24, of Mill Street, Greasborough, Rotherham, Stewart Graham, 31, of Norfolk Park Road, Sheffield, Daniel Hallgate, 24, of HMP Thorpe Arch, Wetherby, Lee Pidcock, 32, HMP Doncaster, Aaron Grahame, 32, of HMP Holme House, Michael Beale, 25, of HMP Wealstun, Jake Johnson, 23, of HMP Everthorpe, James Kelly, 27, of Pendlebury, Manchester, Kyle Sherlock, 24, of HMP Hull, Paul Dempsey, 36, of HMP Doncaster, Mark McLean, 23, of Cheapside, Worksop, Ryan Sturman, 23, of HMP Hull and Nathan Willoughby, 24, of New Park Estate, Stainforth, Doncaster.
