OMAHA, Neb. (AP) — A man who punched a police officer so hard the officer’s face was shattered has been given 15 to 20 years in a Nebraska prison.

Thirty-two-year-old Chaz Hill was sentenced Tuesday in Douglas County District Court. A judge gave Hill 335 days credit for time served. Hill had pleaded guilty to assault on an officer.

Police say Officer Tom Arrance responded to a disturbance at a gas station Oct. 7 and confronted a man who witnesses say was acting oddly. Police say Hill punched Arrance just once, breaking the officer’s nose, a cheekbone and the bones around one eye. Doctors used six metal plates and 17 screws to repair the damage.

Witnesses say Hill appeared to try to remove Arrance’s gun from its holster before fleeing.
