Warren police are investigating after a shooting overnight.

Police received calls from neighbors around 11:30 p.m. Monday about fighting and gunfire heard near Hamilton street.

A short time after those calls were made, a man checked into Trumbull Memorial Hospital with a gunshot wound.

His condition and the circumstances leading up to the shooting are still unknown.

Shell casings were found in the 2500 block of Hamilton street, and it appeared a house had been sprayed with bullets.

A neighbor who called 911 for help, said about two dozen gun shots were heard in the area.
