The Boston Police Department reports arresting two men and a woman on charges they used a sawed-off shotgun to rob a man from his phone and a large amount of cash late Wednesday night in the parking lot of the Walgreens pharmacy at Morton and Norfolk streets in Mattapan.

Police say the victim was approached by three people around 11:40 p.m. After taking his Samsung Galaxy Note, driver's license and cash, they jumped into a late-model Chevy Malibu and sped off, police say.

Police say officers spotted the car stopped for a red light outbound on Blue Hill Avenue.

Jasmin T. Cobb, 25, of Dorchester, Jermaine O. Omoregie, 23, of Milton, and Neil E. Tom, 23, of Dorchester, were charged with armed robbery, assault by means of a dangerous weapon and possession of a sawed-off shotgun - which police say they recovered from the car.
