Two men dressed in all black clothing robbed the employee of an emissions shop on Ga. Highway 138 north early Monday evening, police said.

The men used a semi-automatic pistol but didn’t get money from the Emissions To Go store, said Lt. Belinda McCastle of the Fayette County Sheriff’s Office. The suspects, who have not been apprehended, forced the employee back into the store where he showed them the empty cash drawer, she said.

The suspects left after the employee gave them an undisclosed amount of cash from his pocket, McCastle said.
