Angry driver smashes into pedestrian, utility box after slamming into car of guy he'd been arguing with in an East Boston bar, police say

State Police report arresting a Chelsea man for some major closing-time street carnage at Bennington and Porter streets this morning that they say left an innocent pedestrian rushed to the hospital, a tree knocked down and a utility box, light pole, bench and his own car and his alleged opponent's car heavily damaged.

WCVB reports the incident started as a heated argument inside a bar a few blocks down Porter around 2 a.m. that spilled into the street, where the verbal jousters both got into their cars.

State Police say that troopers arrived on scene in time to see a drunken Adelmo Rodriguez, 47, of Chelsea, trying to free his Corolla from the utility box his car wound up stuck to after he'd driven in reverse into it - and that he directed his anger at them:

As Troopers arrived, the driver was attempting to dislodge the vehicle by aggressively accelerating forward and backward and in the direction of the troopers.

State Police add:

Preliminary investigation indicates a pedestrian had been struck and was located lying on the sidewalk. Boston EMS responded and transported the pedestrian to an area hospital for injuries. A second vehicle was also struck and located with heavy damage rendering it inoperable. The occupants of that vehicle were not injured.

State Police and WCVB report that in addition to the other car, the pedestrian and the utility box, Rodriguez also took out or damaged a light pole, a tree and a metal bench.

State Police add that Rodriguez eventually complied with troopers' demands to get out of what was left of his car and lie on the ground so that he could be arrested on a variety of charges: Attempted murder, assault with a dangerous weapon, OUI, two counts of assault and battery on a police officer, reckless operation, leaving the scene of an accident causing personal injury, leaving the scene of an accident causing property damage, resisting arrest, threatening to commit a crime, driving without a license and marked-lanes violation.

Innocent, etc.
