The owners of three individual restaurants in Cumberland County have been indicted in recent months as part of a statewide sweep by the Maine Revenue Services to crack down on eateries accused of withholding sales tax. The owners of J’s Oyster Bar in Portland, Anjon’s Italian Restaurant in Scarborough and DiSanto’s Restaurant in Gray are the latest to be indicted on a slew of charges, including a Class B charge of felony theft by misapplication of sales tax against each of them. Assistant Attorney General Gregg Bernstein, who is prosecuting the cases brought by the Maine Revenue Services, wouldn’t say on Friday how many other cases are being brought against restaurants around the state.
