An elderly Pennsylvania man held up a bank in Council Bluffs this morning, but his ultimate goal wasn’t getting the money. Cops say the 76-year-old walked into the People’s National Bank at about 11 o’clock this morning.Council Bluffs police sergeant Ray Mabbitt says the man walked into the bank and handed the tellers a note demanding two, 50-dollar bills. The clerks weren’t sure he was serious, but they gave him the money. As he left the bank, the robber announced he’d be in his car, smoking a cigarette. When cops arrived, Marvin Stewart of Pittsburgh, Pennsylvania was waiting. Stewart told ’em he robbed the bank because he has no family members and wants to go back to federal prison.Stewart is now in the Pottawattamie County Jail. He COULD face federal charges for holding up a bank — and wind up back in a federal prison.
