OMAHA, Neb. (AP) — A veteran Omaha police officer who has been accused of domestic assault will be fired.

Omaha Police Chief Todd Schmaderer said Tuesday that he is recommending terminating 41-year-old Christopher Duffek now that an internal investigation is complete.

Authorities said Duffek was arrested on suspicion of domestic assault on Aug. 8 after an argument with his girlfriend. She had injuries consistent with assault.

Duffek has pleaded not guilty to the assault charge, and he is tentatively scheduled for trial next month.

Duffek has been on administrative leave since his arrest. He will have a hearing before he is fired, and he has the right to appeal.

Duffek is a 15-year-veteran of the Omaha department.
