According to Chamblee police, the taxi driver said she picked up the passenger at the Chamblee MARTA station and transported him round trip to the Wells Fargo.
Upon their return to the MARTA station, the man told the driver he needed to go to the station parking lot to get money out of his car to pay for the trip.
The driver, concerned her passenger was going to skip out without paying, blocked his car with the taxi and got the attention of a MARTA officer. The officer didn't know about the bank robbery and talked Gladston into going back to the bank to withdraw money to pay for the cab ride.
When the suspect went back into the bank to get money to pay for his taxi ride, bank employees informed police officers (who had by then arrived) that he was the robber. Police then arrested the suspect.
