The Orono branch of Bangor Savings Bank was robbed shortly after noon Tuesday.
According to Orono Police, no one was injured during the robbery.
"The report was a male came in wearing a grey, hooded sweatshirt, a black mask, sunglasses. Handed them a note with some instructions that he wanted money. He implied that he had a weapon. He took an undisclosed amount of cash and left the bank on foot.," said Chief Josh Ewing with Orono Police.
An intensive search was conducted by nearly two dozen police officers, but the suspect managed to elude capture.
Chief Ewing says investigators are trying to determine whether this robbery is connected to Sunday's robbery of a convenience store in Milford.
The police chief says this the second time within the past several years this branch of Bangor Savings Bank has been robbed.
