An officer at Oakhill youth detention centre is fighting for his life after he was allegedly attacked by five young inmates.
The man, who is only 21, has been airlifted to John Radcliffe hospital at Oxford with critical head injuries.
It is understood that Five youths, aged 13 and 17, have been arrested by police on suspicion of attempted murder.
The alleged attack is believed to have taken place on the unit’s football field at around 6pm yesterday (Wednesday).
Oakhill, designed to be a secure training unit for up to 80 young offenders, was rated ‘inadequate’ in promoting positive behaviour by Ofsted earlier this month.
Inspectors had found makeshift weapons hidden in the rooms of detainees.
They were also concerned about a number of violent incidents resulting in 54 injuries to staff and inmates, with seven of the injuries serious enough to require hospital treatment.
The Ofsted report said an ‘inconsistent’ approach to violent episodes meant some perpetrators “faced little or no consequences.”
Oakhill is currently in the process of being sold off by G4S security and it is understood staff are complaining of shortages.
