FARGO, N.D. (AP) - A former North Dakota doctor accused in an Internet prescription fraud case has been sentenced to three years of probation.

Enrique Rivera-Mass had pleaded guilty in federal court to conspiracy to distribute controlled substances. Authorities say he illegally signed off on prescriptions for nearly 1.8 million pills
that were sold online.

The defendant's attorney, Jose Barreto, says his client met the criteria for a sentence of probation. He says Rivera-Mass has no criminal history and cooperated with authorities.

U.S. District Judge Ralph Erickson ordered Rivera-Mass to serve 90 days in a halfway house in his native Puerto Rico, and nine months on home confinement.

Erickson says Rivera-Mass must perform 500 hours of community service.
