BANGOR — A Greyhound bus driver who is a suspect in 10 bank robberies in four New England states has been indicted on federal bank robbery charges in the state of Maine.

The Bangor Daily News says 47-old Robert Ferguson of Lowell, Mass., is due to be arraigned Monday in U.S. District Court in Bangor on charges he robbed an Orono bank last month.

The FBI had offered a reward for help catching the suspect in at least 10 bank robberies in Massachusetts, Rhode Island, Connecticut and New Hampshire. The FBI dubbed the suspect the “burly bandit” because of his stocky build.

Officials have not publicly said they believe Ferguson is the burly bandit, but he has been charged in Rhode Island with one of the robberies attributed to the suspect.
