(Washington) Ex-athletic therapist Larry Nassar, who was convicted of sexually assaulting multiple gymnasts, was stabbed multiple times during a fight involving another inmate at a federal prison in Florida.

Two people familiar with the situation told The Associated Press that the attack happened at the United States Penitentiary Coleman in Florida. Those sources said he was in stable condition as of Monday.

One of these people specified that he had been stabbed in the back and chest.

These individuals were unable to publicly discuss the incident or the ongoing investigation, and requested anonymity in order to speak with The Associated Press.

Nassar served decades in prison for sexually assaulting several gymnasts, including some Olympic medalists.

Nassar is currently serving his prison sentence after being found guilty in state and federal courts. He admitted to sexually assaulting athletes while working for Michigan State University and USA Gymnastics, which trains Olympic athletes. Nassar also pleaded guilty to charges of possession of child pornography.

During hard-hitting victim testimony in 2018, several athletes said they told adults — including coaches and therapists — about Nassar’s actions, spanning more than two decades, without ever being formally investigated. .
