Sports doctor and convicted molester Larry Nassar was reportedly assaulted in prison. The attack could result in him being transferred to another facility.

The assault occurred within hours of Nassar’s release to the general population at the United States Penitentiary in Tucson, Arizona. His attorneys have blamed the attack on Judge Rosemarie Aquilina, who sentenced Nassar to 40 to 175 years in prison in January. They claimed that she signed his “death warrant,” citing her “efforts to demonize Dr. Nassar in front of the entire world.”

The attorneys have also filed a motion for their client to be resentenced by a new judge. They argued that Aquilina’s sentence is invalid because she is “admittedly not an unbiased and impartial judge.”

Nassar is currently serving a 60-year prison sentence on child pornography charges. He will only serve the sentence handed down by Aquilina, which was based on the testimony of more than 200 women who accused him of molesting them, including Olympic gymnast Jordyn Wieber (pictured), while he was working as a sports doctor at Michigan State University and USA Gymnastics.

Ralph Miller, a retired Bureau of Prisons employee, told The Detroit News, “Part of the mission statement of the Bureau of Prisons is to house inmates in facilities that are safe and this will be a priority, if it is determined that Nassar needs to be transferred.”
