The Nebraska Correctional Services Department says the assault occurred around 4 a.m. Thursday at the West Campus of Bryan Medical Center.
Nebraska Penitentiary prisoner Robert Carter had been taken to the hospital on Sunday for treatment. The department says the officer was watching Carter in a restroom when Carter yelled at him, hit him in the head and turned to leave. The department says that when the officer told Carter to stop, Carter turned and stabbed the officer with a metal butter knife.
Cuts to the officer’s head, neck and an ear were treated at the hospital, and he was released.
Carter is serving a 30-year sentence for attempted assault on an officer and several other convictions.
