Chico police are looking for a man they say stabbed another man in the back early Saturday morning. Investigators say two men got into an argument outside The Beach, which is a bar on East 2nd Street. They say the victim walked outside, and that's when he felt like he was punched in the back. He began bleeding from a stab wound, when workers from the bar came out to help stop the bleeding while waiting for an ambulance to arrive. The man's wound is not considered life-threatening.
