Arlington Police report arresting a pair of alleged knuckleheads they say pummeled a cab driver when he insisted they pay their fare after a ride from Alewife station late Saturday.
Christopher LaFrance, 25, of Arlington, and Jacob Shaps, 24, of Boston, were arrested on charges of assault and battery, unarmed robbery and intimidation of a witness after police tracked down LaFrance's residence based on the ID cards he left behind in the cab's back seat, police say.
According to police, the cab driver picked the duo up at Alewife around 11:30 p.m. and drove them to Arlington, telling them the ride would be about $20.
