A FATHER has exploded with rage in open court and tried to attack the paedophile doctor who abused his three daughters.

The dramatic moment occurred in Michigan during the third and final sentencing hearing for disgraced former Olympic doctor Larry Nassar, who has been convicted for sexually abusing more than 100 women and girls under the guise of medical treatment.

The father of three victims, Randall Margraves, was given the chance to address the judge on Friday and he took the opportunity to make an unusual request.

"I would ask you, as part of the sentencing, to grant me five minutes in a locked room with this demon. Would you do that?" Mr Margraves asked, with his daughters looking on.

When the judge refused he asked "Would you give me one minute?"

When the judge refused a second time, Mr Margraves went berserk, leaping over a podium and charging at Nassar with a raised fist.

Mr Margraves was quickly tackled to the ground by security guards.

"I want that son of a bitch. Give me one minute with that bastard," Mr Margraves added as he was carried out of the courtroom in handcuffs.

Mr Margraves stared at Nassar and grew visibly enraged as victim statements were read out on Friday that detailed his hideous crimes, for which he has been sentenced to a maximum of 175 years in jail.

"You cannot behave like this. This is letting him have his power over us," prosecutor Angela Povilaitis said after Mr Margraves' outburst.

"You haven't lived through it, lady," Mr Margraves shot back.

At his sentencing, Judge Rosemarie Aquilina told Nassar she had "just signed his death warrant" because he "did not deserve to walk outside a prison ever again".

His "decision to assault was precise, calculated, manipulative, devious, despicable", she said.

"It is my honour and privilege to sentence you," she said.

"You have done nothing to control those urges and anywhere you walk, destruction will occur to those most vulnerable."
