The victim told police that he had gotten back into his car after pumping gas at a convenience store at Millbrook Road and Atlantic Avenue around 2:45 p.m.
The carjacker entered the passenger side of the car and ordered the victim to drive out of the parking lot and turn west onto Millbrook, said Jim Sughrue, a spokesman for Raleigh police. The carjacker was armed with a handgun, Sughrue said.
The carjacker forced the victim to stop at Millbrook and Windy Hill, less than half-a-mile from the convenience store, police said. Investigators said the carjacker took the victim's wallet and then fled in his car.
The carjacker's gun discharged during the robbery, but the victim was not struck by the bullet, Sughrue said.
Police described the carjacker as a black man, probably in his early 20s, who stands about 6 feet tall and weighs approximately 180 pounds. He wore a white T-shirt with black lettering and khaki-colored shorts that went below his knees. He also had a black, nylon backpack with thin straps.
The stolen vehicle is a light blue, four-door 1998 Nissan Sentra. The car's rear windows are tinted, and it has a bullet hole in the windshield as a result of the shot fired during the robbery.
