VERGENNES — Vergennes police on Nov. 2 worked with federal law enforcement and the Bank of America’s fraud department to prevent a fraudulent check for about $6,900 being charged to a city law firm.

A representative of the law firm reported to city police a check written to a fire protection firm had at some point been altered from $115 to $6,900. City police contacted Bank of America and said it was determined the check was being held at a postal processing center in North Attleboro, Mass.

Federal law enforcement and bank officers determined the identity of the person who had deposited the check and were able to halt the transfer of funds, city police said. As of earlier this week an arrest of a Massachusetts resident was believed to be imminent, they added.
