Two of Randall Margraves' daughters were among the 265 girls molested by Nassar.
A dramatic scene unfolded Friday when the father of three daughters accusing Larry Nassar of sexual abuse lunged at Nassar in a courtroom.
In Friday's courtroom appearance, Margraves had demanded "five minutes alone with that demon", and when the judge refused, asked for one minute.
"I delivered, unintentionally, my three daughters to a demon", he said, expressing his angst as a parent.
"And I look over here and Larry Nassar's shaking his head no like it never happened, who would put themselves through this if it didn't happen. I can only hope that when the day comes when Larry Nassar has ended his days on earth" that he goes to the "deepest, darkest, hottest pit in hell there is".
Margraves was handcuffed and taken into custody. As uniformed officers pulled him from the courtroom, he implored them, "What if this happened to you guys?" "Give me one minute with that bastard".
"My daughters are the real heroes and all the victims and survivors of this", Margraves said during a press conference Friday evening.
Morgan Margraves says her father was hearing some details for the first time. When the judge gave him permission, Margraves began, "You son of a b--", before the judge cut him off for using profanity.

Following the recess in Friday's proceedings, the judge declined to cite Margraves for contempt of court.
"There is no way that this court is going to issue any type of punishment given the circumstances of this case", Cunningham told Margraves after he apologized a "hundred times", according to reports.
Nassar, the former USA Gymnastics team doctor and Michigan State doctor, is facing his third sentencing for sexual assault and molestation.
In the latest fallout from the scandal, Valeri Liukin, the coordinator of the USA women's gymnastics team, said on Friday that he was resigning. Valeri Liukin said in a statement that while he wanted to help turn the program around, "the present climate causes me, and more importantly my family, far too much stress, difficulty and uncertainty".
Cunningham said Nassar didn't authorize the statements and has disavowed them.
