A Milwaukee County Sheriff’s Office corrections officer was punched in the face by an inmate at the County Correctional Facility-Central late Thursday night, according to the Sheriff's Office.
The officer suffered a concussion, fractured sinus and facial lacerations.
"Some creep injured an officer in a cowardly unprovoked attack," Milwaukee County Sheriff David Clarke said in a news release. "Acts of cowardice are how criminals behave."
The inmate was subdued and was put into solitary detention.
The Sheriff's Office said it will seek criminal charges against the inmate.
