The bureau is seeking the public's help in finding the man dubbed the "Beach Bum Bandit" because of his casual attire that included baggy shorts. He's thought to be responsible for at least three robberies at suburban banks since mid-May.
The first occurred in Roselle at the Mutual Bank branch at 801 E. Nerge Road on May 8, and the same robber is suspected of returning again on May 22. The most recent incident occurred June 4 in Rolling Meadows at the MB Financial Bank branch at 2251 Plum Grove Road.
A witness at the last robbery said the suspect entered the bank, announced the robbery and ordered an employee to fill a blue-fabric bag with cash. He then fled the scene on foot and left the area on bicycle, authorities said.
No injuries were reported in any of the robberies, though the FBI considers him dangerous because he was armed with a handgun.
The suspect is described as a white male with brown hair, 20 to 25 years old and about 6 feet tall with a thin build, weighing 170 to 190 pounds. During two of the robberies he wore a bandanna or scarf around his face. In surveillance images, he's shown with a brimmed hat in one robbery and a University of Miami baseball cap in another.
The Chicago FBI branch and investigators from the Roselle and Rolling Meadows police departments are carrying on a joint investigation. Anyone who recognizes the man or has information about the robbery is asked to contact the Chicago FBI at (312) 421-6700.
