The report said there was no increase in violence but that vulnerable prisoners were “subject to cat-calls and abuse” as they had to be escorted through locked-down general areas.

Sodexo said there had been no recent issues regarding vulnerable inmates at the prison.

The report also said there was “widespread drug use and availability” at the men‘s site, and was concerned by the level of violence.

But it praised a prison-run programme, Outside Links, for its “excellent work” helping prisoners on their release.

A Sodexo spokesman said: “We welcome the findings of the IMB annual report, which has found prisoners to be treated fairly with good support extending into the community for their release… Successful rehabilitation relies heavily on these factors.

“Common to the rest of the prison estate, drugs and violence are a challenge at HMP Peterborough, and the report recognises our continued focus on keeping prisoners safe and on efforts to reduce violence.”
