Norwood Police are investigating an Aggravated Robbery that occurred on January 13, 2014 at 8:46pm. A light-skinned black male dressed in all black and wearing a white face mask entered the BP Gas Station at 4900 Montgomery Rd waving a black semi-automatic handgun. He demanded money from the clerk and after the clerk complied, he started towards the door, but turned back and pointed the gun at the clerk. The suspect is described as 5’9″-5’10” tall, medium build with a white mask with a hole in the forehead area, the eyes and the mouth. Detectives say that he may have been wearing sunglasses. The vehicle of interest is not the auto parked just outside the glass window, but the black vehicle that cruised through the parking lot.
