The FBI is looking for the public's help in locating a suspected bank robber dubbed the "hobo bandit" because he sported a shaggy beard, a tattered baseball hat and a long trench coat during several recent Atlanta robberies.

The FBI says Wednesday the suspect is wanted for three Atlanta bank robberies that began in November 2009. The most recent took place Tuesday, when police say the suspect struck the Chase Bank in north Atlanta.

The FBI says the suspect is a white male in his 40s to 50s who weighs about 180 pounds. He often wears a hat and dark sunglasses. FBI officials believe he likely lives in the Atlanta area.

Anyone with information is encouraged to call the FBI's tip line at (404) 679-9000.
