Rapid City police are looking for a man who robbed an Exxon convenience store.
Authorities say the man entered the store about 1:00 a.m Friday, collected several items and then threatened to fire a gun at the clerk.
Lt. Don Hedrick says the man did not actually display a gun but led the clerk to believe that he had one.
The suspect is described as a Native American man, about six feet tall, 180-200 pounds. He was wearing a dark coat and shirt.
Witnesses saw the suspect leave the store in a gray or silver Chevy Camaro (1990's model).
