Larry Nassar, a predatory felon convicted of molesting young, female gymnasts for decades, was stabbed multiple times by a fellow inmate at a federal prison in Florida Sunday, the Associated Press reported.

The altercation took place at the United States Penitentiary Coleman in Sumterville, Florida, two people familiar with the matter who were not authorized to publicly discuss the matter told the AP.

Nassar was in stable condition Monday after being stabbed in the back and in the chest, according to one of the AP's sources.

Nassar was sentenced in 2018 for up to 175 years in prison after decades of sexually abusing more than 150 women and girl gymnasts, CNN reported.

Nassar was convicted of sexually assaulting his many victims while employed as a osteopathic doctor by Michigan State University and USA Gymnastics.

Nassar was also separately convicted on federal child pornography charges in 2017, the IndyStar reported. He had at least 37,000 videos and images of child pornography, investigators said.

Nassar pleaded guilty to 10 counts of first-degree criminal sexual conduct. He abused nine of those 10 victims during medical appointments by digitally penetrating them, the Star also reported.

Nassar's Michigan victims were all younger than 16. Three were younger than 13.

More than 90 young women, including Olympic gymnasts Simone Biles, Aly Raisman, and McKayla Maroney, sought $1 billion in damages in a tort claim against the FBI in 2022, as TheBlaze reported.

The woman say the bureau failed to act on the sexual assault allegations against Nassar.

"My fellow survivors and I were betrayed by every institution that was supposed to protect us — the U.S. Olympic Committee, USA Gymnastics, the FBI, and now the Department of Justice," Maroney said in a statement at the time.

"It is clear that the only path to justice and healing is through the legal process."
