FBI and Conyers police investigators are on the search for a suspected serial bank robber that struck the Wachovia branch off Dogwood Drive near the IHOP restaurant Tuesday shortly before noon.

CPD Lt. Jack Dunn said a black male wearing a black cap, one or two days worth of facial hair, and a striped shirt around his neck approach a teller and handed her a note. The note reportedly demanded money and indicated he had a weapon. The teller complied and the suspect left the bank on foot.

"He appears to be someone who has have hit other metro area banks," Dunn said. "When we communicated with FBI they seemed to recognize him."

Security camera footage showed the man running toward the Home Depot parking lot, said Dunn. Investigators believe he left the area in a vehicle.

The branch, which is located near the entrance to Interstate 20, has been previously robbed, as recently as this year, said Dunn.

The robbery was apparently so quiet other customers in the bank did not realize what was happening.

One person who had been in the bank at the time said he had been talking with an employee at a desk near the front when he heard a cashier suddenly say, "Let's lock it down."

"I was kind of dumbfounded," said the customer. "I had no idea it was going on... They were very calm."

The bank was locked down until police arrived to conduct interviews and search the area.

Anyone with information on the suspect or the incident is asked to call the CPD at 770-483-6600.
