Judge drops sexual assault charges against California doctor and his girlfriend

A California judge has dismissed sex charges against a Newport Beach surgeon who previously appeared on reality a television show, and his girlfriend after they were accused of drugging and raping women in a case that drew international attention.

Court records show that charges of assault with the intent to commit a sexual offense were dismissed Friday against Dr. Grant Robicheaux, a surgeon who appeared on a Bravo TV show called "Online Dating Rituals of the American Male," and girlfriend Cerissa Riley.

The decision came after a preliminary hearing before Superior Court Judge Michael Leversen, who determined there was not sufficient evidence on the sex charges to proceed to trial, the Orange County Register reported.
