Bank surveillance pictures of the suspect have been released. He's wanted for two bank robberies in the western suburbs and one attempted bank heist in April.
The suspect is between 60 and 70 years old. He has graying black hair and is missing several teeth from his lower jaw.
The FBI says they call him the Over the Hill Bandit because of his unusual age for a serial bank robber.
Anyone with information is asked to call the Chicago office of the FBI.
