Olympic gold medalist McKayla Maroney has revealed that she was sexually abused by the former USA gymnastics doctor for seven years. 

Maroney, 21, said on Tuesday night that convicted sex offender Dr Larry Nassar molested her from the age of 13 until she left gymnastics last year. 

The abuse happened at many high-profile competitions, including the 2012 London Olympic Games where she won gold and silver medals, Maroney said.  

She opened up about the experiences in a tweet inspired by the 'Me Too' movement, which encouraged women to identify themselves as victims of sexual harassment or assault following the Harvey Weinstein scandal.
