OMAHA, Neb. (AP) — An off-duty Omaha police officer needed surgery after being shot in the stomach while visiting a friend’s home on the northwest edge of the city.

Douglas County Sheriff Tim Dunning says the incident that happened Monday morning in a barn near Bennington appears to have been an accident.

The 38-year-old officer’s friend was holding a .357 Magnum that went off and wounded the officer.

Authorities didn’t immediately identify the people involved in the incident Monday.

Omaha police said the officer was in stable condition Monday.
