There has been an increase in violent behaviour among prisoners at a privately-run jail in Nottinghamshire.
But a new report from the Board of Visitors says Lowdham Grange is doing better overall than the Prison Service strictly requires.
It has been designated a four-star establishment and the report says the work of the prison is encouraging.
Since January prisoners have not had to share a cell. But the number of times staff had to use force went up to 39.
A member of staff was taken hostage last August and six prisoners got drunk on hooch and barricaded themselves in a cell where one threatened to harm himself and others.
Prisoners with serious health problems have increased in number. And there were 42 finds of drugs, an increase on the previous year.
A report this time last year found Lowdham Grange had seen big improvements in the previous 12 months, according to a report by the Independent Monitoring Board.
