FALL RIVER, Mass. (AP) _ Police say a shooting in Fall River earlier this week was sparked by an argument over a stolen dirt bike.

A 32-year-old man was shot and two men were arrested in connection with the shooting Monday night. Police also seized an AR-15 assault-style rifle, although it's unclear if it was used in the shooting. Witnesses say the shooter used a silver handgun.

The Herald News reports that police arrested 21-year-old Chad Guilmette, who they allege is the gunman, on charges including armed assault to murder; as well as 26-year-old Christopher Pettey on accessory charges.

The AR-15 was found in the attic of the apartment building in which the suspects live.

Two people who were with the victim told detectives their group confronted another group about a stolen dirt bike.
