Three men were arrested on suspicion of illegal gun possession after a routine traffic stop in Vallejo on Sunday afternoon, a police lieutenant said.

Around 3:35 p.m. Sunday, an officer conducted a traffic stop of a vehicle in the 1600 block of Fairgrounds Drive, Lt. Kenny Park said.

The officer determined that the car's driver was a probationer who is subject to search and seizure. A search of the car turned up a loaded handgun and live ammunition, Park said.

All three men in the vehicle were arrested. They were identified as 30-year-old Vallejo man and convicted felon Dondi Davis, Steven Henderson, 45, and Carlos Addison, 55, both of Oakland.

Park said that while the arrests took place not far from the scenes of three separate shootings in Vallejo Saturday night, police have not determined any link between the suspects and any of the shootings.

"As far as we're concerned, we're treating them as separate incidents," he said.
