A Fremont man convicted of assaulting a police officer has been sentenced to prison.

The Fremont Tribune reports that 28-year-old Patrick Patterson was sentenced Monday in Dodge County District Court to four to five years in prison for third-degree assault of an officer.

Authorities say police were trying to escort Patterson from a bar when Patterson punched one of the officers in the side of the face, breaking the officer’s glasses. Another officer was injured as a result of a stun gun that was used to subdue Patterson.

Patterson has said he does not remember the incident.
