A motorist was arrested in Medford Tuesday afternoon for allegedly pointing a gun at another driver following a road rage incident, the Massachusetts State Police said.

Gary Pimental, 20, of Charlestown, was handcuffed at the scene and charged with disorderly conduct and assault with a dangerous weapon.

Around 4:30 p.m., Medford police responded to the ramp of Route 93 northbound to Mystic Avenue after receiving a phone call from the victim. Officer Danny D'Amica stopped Pimental, who was driving a Honda Accord. D'Amica phoned state police for assistance at the scene.
