A man accused of attempted murder has been charged with attacking a correctional officer Thursday morning at the Cook County Jail.

Peter Williams, 45, was speaking with the correctional lieutenant about 9:40 a.m. at the jail’s super maximum security Division 9, 2834 W. 31st St., “regarding a complaint of contraband being removed from his cell,” according to a statement from the Cook County Sheriff’s Office. After speaking to the lieutenant for about two minutes, Williams punched him in the face.

The lieutenant was taken to a hospital with facial injuries, the sheriff’s office said.

Williams was charged Thursday with aggravated battery to a peace officer, aggravated battery causing great bodily harm and aggravated battery in a public place.

He has been in custody for nearly four years on an attempted murder charge out of Harvey, according to the sheriff’s office. He has been involved in 20 “fighting incidents” during his time at the jail.
