Here's some facts about Olney prison

Did you know?

HMP Onley is a category C prison in Barby, Northamptonshire. Opened in 1968, the prison has capacity to hold 742 adult male inmates.

The prison’s residential unit consists of wings A-I. A, B, C, D and E wings each hold 60 prisoners. F wing is the segregation unit, consisting of 15 cells. G wing is the resettlement wing, holding 60 prisoners. H wing is the first night and induction unit, holding 60 prisoners. I wing holds 100 prisoners. J and K wings each hold 76 prisoners and L wing, the enhanced wing, holds 70 prisoners.

In late 2016, a rise in violence was discovered, and blamed on the conversion in 2013 to a resettlement prison for Greater London. Inspectors found there had been a “dramatic incline ” in standards in that time. “Staff gave various explanations, including the change of prisoner population and gang-related issues that they brought with them, the impact of new psychoactive substances (previously known as “legal highs”) and the impact of reductions in staff numbers,”
