BANGOR — Police are looking for a white Ford sedan involved in a hit-and-run accident with three vehicles at a stop light on Union Street Friday evening. Two people were treated at a hospital and released while a third victim was still being evaluated three hours after the accident.

Three cars were lined up at a red light on Union Street at the Main Street intersection at about 7:30 p.m. Friday when the white sedan drove into the last car in line, starting a chain reaction.

The driver of what is believed to be a Ford Taurus then drove around the other vehicles, continued across Main Street and headed across the Joshua Chamberlain Bridge into Brewer, according to Patrolman Brian Veysey of the Bangor Police Department.

The first car struck was an Airport Taxi 1987 Ford station wagon driven by Tommy Hart, 32, of Bangor. Hart was not injured, but later wound up being summoned for driving with his license under suspension.

The taxi was pushed into a 1984 Buick midsize sedan driven by Colin Shields, 65, of Bangor. There were four passengers in Shields’ vehicle — Richard Niles, 57, of Bangor; Susan Sweaney, 46, of Bangor; Sandra Munson, 55, address unknown; and Roland Partridge, 45, address unknown. Patrolman Veysey said Niles and Sweaney were not injured but that the other three people in the vehicle suffered neck injuries. A spokesperson at Eastern Maine Medical Center later indicated that Munson and Partridge had been treated and released. Shields was still being evaluated at 10:30 p.m.

The final domino struck in the chain reaction was a 1985 Volvo driven by Andrew Scott, 17, of Brewer, who was uninjured.

Patrolman Veysey said damage to the vehicles was minimal. He estimated damage to the cab at $500, the Buick at $400, and the Volvo at only $25.

Anyone with information about the accident is urged to call the Bangor Police Department.

“Hit-and-run involving injury is a serious offense,” said Veysey.
