Michigan's attorney general says charges against a former USA Gymnastics team doctor are the "tip of the iceberg" as authorities investigate roughly 50 complaints filed with police.
Bill Schuette said Tuesday that Larry Nassar of Holt posted bond after he pleaded not guilty earlier in the day to three counts of first-degree criminal sexual conduct in his home with a girl under 13. The alleged assaults occurred between 1998 and 2005.
Schuette says the girl wasn't a gymnast, a patient or a family member.
He says his office is working with the FBI and a U.S. attorney's office in Michigan.
The 53-year-old doctor has been under scrutiny since two gymnasts, including a member of the 2000 U.S. women's Olympic team, accused him of sexual abuse during medical treatments.
