CHICAGO, Nov. 22 (Xinhua) -- Former U.S.A. Gymnastics doctor Larry Nassar pleaded guilty on Wednesday to multiple charges of sexual assault under the guise of medical treatment.
Nassar, 54, made the admission for the first time in Ingham County Circuit Court, Michigan state, local media reported.
Each of the counts of first-degree criminal sexual conduct is punishable by 25 to 40 years in prison.
Nassar worked as a team doctor for the Michigan State University Gymnastics and served as the U.S.A. Gymnastics physician through four Olympic Games.
More than 100 victims of the disgraced doctor have reported sexual assaults to police, including several Olympic medalists from the team of American gymnasts.
Many of the victims were teenagers when they were sexually abused by Nassar, with his hands, during medical treatments.
Following the disclosure of the scandal, the former head of U.S.A. Gymnastics resigned and the organization adopted a series of measures this year in order to prevent future cases of abuse.
