Arthur Roberts is in hot water with the Massachusetts Attorney General’s Office ― the agency whose letterhead he allegedly forged when he secured a $22,000 auto loan.

The Office of AG Martha Coakley began investigating Roberts’ alleged activities last fall, after receiving information that Roberts had used fraudulent documents to dupe an auto finance company into granting him a loan.

Here’s how the alleged scam went down: Roberts, 63, tried to cover up a previous repossession by telling the dealership’s business manager that his identity had been stolen. To support his claim, Roberts allegedly submitted some forged documents ― one purportedly from the AG’s Office, and two that appeared to be written by a credit bureau employee. The letters indicated that the agencies were investigating the ID theft claims.

On March 30, a Norfolk County, Mass., Grand Jury returned indictments against Roberts. He awaits arraignment.

The case is being prosecuted by Assistant AG Jill Ambrose of the Fraud and Financial Crimes Division.
