A video surveillance shows three inmates beating up two correctional officers at Cook County Jail on Wednesday night. Sheriff Tom Dart is seeking attempted murder charges on the three inmates.

The incident happened around 8:30 p.m. in a housing tier of Division 9, a super maximum-security part of the jail. The video shows the inmates beating up the two correction officers who were able to get away through a door. A storm of correctional officers than come to the housing tier to defuse the situation.

Two of the detainees suspected in Wednesday’s attack – 19-year-old David Bush and 20-year-old Taiwan McNeal — are being held on charges of attempted murder for allegedly shooting an off-duty Oak Park Police officer in 2015, the sheriff’s office said. A third detainee, Terrence Lynom, 20, has been in Cook County Jail since 2014. He allegedly shot a 6-year old-girl while she rode her bike in the Roseland neighborhood.

The two officers were taken to the hospital and treated, one had a fractured orbital and the other officer lost consciousness
