Charlotte, Mich. — A distraught father seething over sexual abuse suffered by three daughters tried to attack former sports doctor Larry Nassar in a Michigan courtroom on Friday after a judge rejected his request to confront the “demon” in a locked room, a stunning rush that reflected the anguish felt by parents who trusted him with their children.

Randall Margraves was blocked by an attorney, tackled by sheriff’s deputies and hauled out of court. He later apologized, saying he had lost control. Eaton County Judge Janice Cunningham said there was “no way” she would fine him or send him to jail under her contempt-of-court powers.

“I don’t know what it would be like to stand there as a father and know that three of your girls were injured physically and emotionally by somebody sitting in a courtroom. I can’t imagine that,” the judge said. Nonetheless, she added, it is “not acceptable that we combat assault with assault.”

“I cannot tolerate or condone vigilantism or any other type of action that basically comes down to an eye for an eye, a tooth for a tooth,” Cunningham said.

The incident occurred during the third and final sentencing hearing for Nassar, who has admitted to sexually assaulting girls under the guise of medical treatment. This case focuses on his work at Twistars, an elite gymnastics club southwest of Lansing, Mich. It follows a hearing last week where Nassar, 54, was sentenced to 40 to 175 years in prison for assaults at Michigan State University and his home.

Nassar pleaded guilty to molesting nine victims in Eaton and Ingham counties, but the courts have been open to anyone who says she was assaulted during Nassar’s decades of work at Michigan State, Twistars and USA Gymnastics, which trains Olympians.
