Police said a man walked into the BB&T branch on Good Middling Drive just before 3:30 p.m. Friday.
Surveillance photos showed the robber holding a gun in his right hand.
He walked up to the teller, showed her the weapon and demanded that she put cash in a bag.
Once he got the money, the robber walked out of the bank and drove off in a silver or gray colored sedan.
Anyone with information is urged to contact police.
