There's been more violence at the notorious Elgin Middlesex Detention Centre in London.

A union official and staff at the facility tell CTV News that a correctional officer was stabbed in the head during an incident Saturday.

At this point, it's unknown the severity of the injuries he or she suffered.

The infamous facility has a growing reputation for violence.

The prison is designed to hold 150 inmates, although it's believed 400 are currently being housed there.
