The FBI is offering a reward for the identity of a man who has successfully robbed several Central Maine banks over the past five years.

He's called the 'Silent Bandit' because he never says a word during his crimes. Instead, he hands the teller a note demanding money and then, when he has the loot, calmly walks away. Police describe him as a heavy-set 55 to 65-year-old white male, between 5'6" and 5'10" tall. He's always wearing a heavy, hooded parka, and has coverings over his face to conceal his features.

Centralmaine.com reports the Silent Bandit is linked to robberies at Franklin Savings Bank in Skowhegan, Key Bank and TD Bank in Waterville, and Bangor Savings Bank in Pittsfield between 2012 and 2015. The above photo was taken from surveillance video at the Pittsfield robbery in 2014.

Anyone who thinks they may have information that will identify the Silent Bandit is encouraged to call the FBI at (857) 386-2000 or the Waterville Police at (207) 680-4700. Tips can also be sent to the FBI tip line.
