Ex Five Wells officer: "inmates run the prison"

Prison operator G4S say "The safety of staff and prisoners is our number one priority, and we do not tolerate violence. Managers take swift and robust action when serious incidents do happen. Such incidents are then referred to the police to support further prosecution. We have sufficient levels of staffing to run a stable, consistent and safe regime. We continue to drive recruitment to increase our staffing numbers which will enable us to broaden our current prison regime."
