A Texas doctor was accused Tuesday in the largest Medicare fraud case in US history, with federal prosecutors charging him with scamming the government with $375 million in phony billings.

Justice Department officials announced that Dr. Jacques Roy was arrested in Texas and faces life in prison as well as fines of more than $250,000 if convicted, according to the Los Angeles Times.

The newspaper reported that Roy and his assistant, who was also charged, sent “recruiters” door-to-door in the Dallas area to get people to sign bogus medical forms that were then used in the alleged scam.
