At about 5:09 PM on Tuesday, September 17, 2019, officers assigned to District C-6 (South Boston), responded to a radio call for a person with a gun in the area of 220 Dorchester Avenue in South Boston.

After further investigation it was revealed that after the motor vehicle accident and before police arrival, Mr. Nguyen was observed exiting his motor vehicle with the Sig Sauer Pistol in his hand as he approached the driver’s side window of the victim’s motor vehicle.
Danh Nguyen was arrested and charged with; Assault by Means of a Dangerous Weapon to wit Firearm, Unlawful Possession of a Firearm, Unlawful Possession of Ammunition.
