New York State Police have arrested a teenager who was allegedly driving with two AR-15 rifles and two 30-round magazines in his car.

Police say the guns and the magazines were not loaded.

19-year-old Maxwell Grimard is from Plattsburgh and was arrested in the city on Monday. Jen Fleishman, a spokeswoman for State Police Troop B, said there was “no imminent threat” of violence at the time of the arrest and Grimard was "cooperative."

Fleishman said the rifles had been illegally modified with pistol grips.

Police charged him with three counts of Criminal Possession of a Weapon in the 3rd degree, a felony. Officers also wrote traffic tickets for driving an unregistered car with a suspended license. Grimard is in custody at Clinton County Jail.
