A Quincy man who was involved in an accident with another motorist on Morrissey Boulevard in Dorchester yesterday was arrested for allegedly stabbing a third driver after that man stopped to complain about the traffic tie-up, according to State Police.
State Police arrested Colum J. Flaherty, 62, shortly after 3 p.m. Flaherty was heading southbound in his 1995 GMC Jimmy when he was rear-ended by a 63-year-old North Reading man operating a 2007 Toyota FJ Cruiser, just before Freeport Street, State Police said. The two drivers were exchanging information when a 54-year-old Quincy man operating a 2010 Honda stopped in front of the two cars and complained about the delay in traffic.
The man and Flaherty became involved in an altercation, during which Flaherty allegedly brandished a knife and stabbed the man. The man, who State police are not identifying, was transported to Boston Medical Center with minor injuries, said State Police spokesman Sergeant Michael Popovics.
Flaherty was arrested at the scene and charged with assault and battery by means of a dangerous weapon, State Police said. He was held at the State Police barracks in South Boston pending bail and is due to be arraigned today at the Dorchester Division of Boston Municipal Court, Popovics said.
The North Reading driver was also not identified.
One state trooper called the incident the worst episode of road rage he had ever seen.
Police closed down two lanes on Morrissey Boulevard for two hours to process the scene for evidence, causing significant traffic back-ups during the evening rush hour.
The incident remains under investigation and more charges may follow, Popovics said.
