The management of Doncaster Prison is pioneering a new approach to cut violence among inmates after figures showed it is the fourth worst in the country.
John Biggin, director of HMP and YOI Doncaster, said: “Serco takes its responsibility for keeping prisoners, staff and visitors safe extremely seriously.
“We have a zero tolerance approach to violence at Doncaster enforced with a particularly tough incentives and earned privileges scheme, which was praised by inspectors in 2010.
“We are also meticulous in our reporting of all violent incidents and its causes, even if it is just a scuffle.
“Our aim is to reduce violence. However we face a number of challenges as it is a full prison with a transient population and a high number of Category B prisoners.”
