The Regions Bank branch at Meadowbrook Road and North State Street in Jackson was robbed about 12:30 Tuesday afternoon.
Cooperation by an alert citizen, and quick work by police resulted in an arrest several blocks away.
Police say the man did not show a weapon but announced that he was robbing the place, and the teller gave him money. He ran out the door and was spotted by an alert citizen, who pointed the robber out to the first police unit on the scene.
The robber was caught and the money recovered. Nobody was hurt.
