According to Sgt. Dana Pierce, three males entered La Tiendita, located in the 2200 block of Powder Springs Road, just south of Macland Road, at around 6:30 p.m.
While one offender approached the female victim at the register, the second and third strategically positioned themselves inside the grocery store. Within moments of doing so, the male at the cash register produced a handgun and demanded the cash drawer from the employee.
After receiving it from the victim, all three individuals fled from the business on foot in an unknown direction.
All three suspects were described as black, standing between 5-foot-9 and 6-feet tall, and in their late teens or early 20s.
The armed male was wearing a gray hooded sweatshirt with a Georgia Bulldogs logo on the front. The other two were wearing hooded sweatshirts.
Anyone with information that may assist investigators with the armed robbery is asked to call 770-499-3945.
