A prison that houses hundreds of sex offenders has been criticised by inspectors for failing to run programmes to tackle their behaviour.
There were riots at HMP Moorland near Doncaster in 2010.
Although a third of prisoners at HMP Moorland, in South Yorkshire, are sex offenders, no treatment programme is available and "too many" of the criminals are released without completing one, HM Inspectorate of Prisons (HMIP) said.
