Bank robber nicknamed the 'American League Bandit' captured, FBI says

The man wore a baseball cap in each of the 12 heists he carried out.

The man's identity and the details of his arrest were not immediately released.

Authorities in Maryland and Virginia had been searching for the man since his first known robbery at a Rosedale Federal Savings & Loan in Baltimore on Nov. 7. He carried out nine robberies and attempted robberies in Maryland, as well as another three in Virginia, according to a FBI press release.

In each robbery, the suspect approached a bank teller and demanded money, the FBI said. After he would receive an undisclosed amount of cash, he would flee on foot.

A $5,000 reward was offered for information leading to his arrest.
