A Morgan Hill man was arrested for battery when he hit a man at the Edmundson Avenue dog park after an argument over picking up another dog's waste, police said.
About 1 p.m. Saturday, officers arrested Max Hamlin, 48, after he verbally fought with and punched another man, who happened to be an off-duty San Jose police officer, in the side of his head, according to Sgt. Jerry Neumayer.
When police arrived, the victim requested to press charges and filled out a citizen's arrest form, police said. When officers are not present to witness certain crimes, mostly misdemeanors, they cannot make arrests. However, a victim or witness may fill out a citizen's arrest form, and the suspect may be arrested, as Hamlin was.
