State Police are hunting for a driver who fled a traffic stop Wednesday night near the CANA tunnel in Boston on Route 1 southbound, nearly striking the trooper and scraping his cruiser, officials said. Police said the trooper pursued the vehicle about 9:15 p.m. along Storrow Drive into the area of Beacon and Gloucester streets where the driver abandoned the car, a 2004 Lincoln Town Car, and fled on foot, breaking into several homes in the area of Marlborough Street.
