Police say the robbery happened at just before 5 a.m. Friday at a Shell gas station at 5821 Limestone Road.
Police say a gas station employee was preparing to open the business when he was confronted by two suspects wearing masks, one of them with a gun and the other with a knife. Police say the employee was forced to lie on the floor, and the suspects bound his hands. The suspects then allegedly stole money from two cash registers, took cigarettes and also took money from the employee's pockets.
The employee was able to free himself and call 911 after the suspects fled.
