A traffic stop in Bend late Wednesday night netted police two shotguns, three arrests, and may have stopped a robbery in the making. Police pulled over a vehicle with five people inside at Third Street and Underwood. The driver was ticketed for having no insurance and walked away with all of the passengers. Police then found a sawed off shotgun and another shotgun. Officers then re-located and arrested the vehicle occupants, but one of the passengers decided to flee on foot. Officers took Spencer Perez, 18, after they caught him. All four face charges for weapon possession and three are charged with conspiracy to commit robbery.
