Officers say the weekend robbery took place at Fast Serve Convenience Store off Martin Luther King Street.
Officers say the suspect didn't use a weapon during the incident, but he was able to get away with an undisclosed amount of cash.
Anyone with information is asked to call the Moultrie Police Department at (229) 890-5500.
"Intimidation robbery is when you commit the offense of robbery without using a weapon. You use threatening words," says Moultrie Police Commander Alfonso Cook.
Investigators say there is a cash reward for anyone with information pinpointing the suspect responsible for the robbery.
