A Bangor man is accused of robbing a bank Wednesday morning. Police arrested Percy Cartwright, 66, at Dorothea Dix Psychiatric Center in Bangor about an hour after the robbery. Police say Cartwright went into Bangor Savings Bank on State Street in Bangor just before 10:30am on Wednesday and demanded money. Cartwright did not have a weapon. Police say bank employees did everything right. ” We talk to banks, we have security briefings we do with banks. Officer Jason McAmbley, our community relations officer, has many different ways that he could teach these security issues to banks and we do that regularly,” said Sgt. Paul Edwards with the Bangor Police Department. Police say they have found all but $20 of the money taken from the bank.
