The enraged father of three daughters sexually abused by Larry Nassar lunged at the former USA Gymnastics national team doctor during a sentencing hearing in a Michigan courtroom on Friday. Court guards pinned him to the ground before he could attack Nassar.

The chaotic scene began after sisters Lauren and Madison Margraves had finished reading their victim statements on the second day of hearings at a court in Eaton County. Stood alongside his daughters and wife, Randall Margraves asked to speak.

"I would ask you as part of the sentencing to grant me five minutes in a locked room with this demon," he said, gesturing toward Nassar, who has already been sentenced to up to 175 years in prison at an earlier hearing after pleading guilty to molesting young women under the guise of medical treatment.

Judge Janice Cunningham told him he knew she could not do that, and chastised him for cursing after he called Nassar a "son of a b****."

He asked for one minute alone instead. The judge demurred as some in the courtroom laughed uncomfortably.

Margraves then bolted towards Nassar, seated in an orange jump suit nearby. Gasps, cries and shouts filled the courtroom as Margraves was wrestled to the ground and put in handcuffs while Nassar was taken out to safety.
