State police arrested a New Bedford man in Dartmouth on April 28 for multiple firearms offenses and other charges after a trooper pulled him over on I-195, according to a release.

Edwin Polanco, 27, of New Bedford was arrested just after 3:30 p.m. Wednesday after a trooper — whose name was not disclosed — noticed the dark window tint of his white Toyota sedan while Polanco was traveling eastbound on I-195, police stated. Dark window tints are illegal in Massachusetts.

The release stated that the trooper then ran his plates and found Polanco’s license was suspended.

Police said that after stopping the car and while waiting for a tow, the trooper inventoried its contents, discovering a backpack containing a large amount of marijuana and a Smith & Wesson 9mm semi-automatic handgun loaded with eight rounds of ammunition.

According to the statement, Polanco’s license to carry a firearm had been suspended in Massachusetts.

Polanco was then arrested and charged with felony firearm possession, possession of a firearm and ammunition without a license, improper storage of a firearm, possession of marijuana with intent to distribute, driving with a suspended license, and a window tint violation.
