MATINICUS, Maine (AP) – Police say the shooting of a lobsterman was fueled by a dispute over fishing territory in the lobster-rich waters off Maine.

Sixty-eight-year-old Vance Bunker was being held Tuesday on $50,000 bail for elevated aggravated assault for allegedly shooting fellow lobsterman Chris Young in the neck with a .22-caliber handgun Monday morning.

Maine State Police spokesman Steve McCausland said tensions between Bunker and Young had escalated to the point where a Maine Marine Patrol officer was called to the island, 20 miles off Rockland. McCausland said the shooting took place on a pier while the officer was on Young’s boat.

Young was flown by plane to the mainland and taken to a Lewiston hospital, where he underwent surgery and was in stable condition.
