FALLS CITY, Neb. (AP) — Law enforcement agencies are combing southeast Nebraska, looking for a car carrying someone who shot a sheriff’s deputy.

The shooting occurred about 2:45 a.m. Monday on Richardson County Road 717 near U.S. Highway 75, about 10 miles south of Auburn.

Richardson County Sheriff Randy Houser says the deputy had noticed a stopped car, so he approached to offer help to the people inside. Houser says several shots were fired from inside the vehicle, which then sped away.

The deputy gave a chase but soon stopped when he noticed that one of his arms had been hit by a bullet.

The officer is being treated in Lincoln. His name hasn’t been released.

No arrests have been reported.
