An Arkansas man is in custody for allegedly robbing a bank in Mustang, Oklahoma. Gregory Gomez of Little Rock was arrested in Canadian County yesterday afternoon, shortly after the robbery. The FBI says Gomez is suspected of posing as a computer repairman and asking to see the bank manager shortly before two yesterday afternoon. Authorities say Gomez then implied he had a gun, demanded money and told the bank manager there were bombs in both his toolbox and a van across the street. He said the bombs would be exploded if police were called. He then took the manager`s sport utility vehicle, which he was driving when stopped by authorities. Money and a loaded gun were found in the SUV. Police say there was no bomb in either the toolbox or the van, which is believed to have been stolen in Arkansas.
