Jean-Luc Brunel has ‘disappeared like a ghost’ as police urgently seek him for questioning.

A key witness, in the child sex trafficking case against deceased pedophile Jeffrey Epstein, has vanished “without a trace” as authorities “urgently” seek him for questioning, according to reports.

Millionaire model agency boss Jean-Luc Brunel, 72, has been described as Epstein’s alleged “fixer” or “provider” of underage girls.

Investigators hunting for Brunel, however, say the Frenchman “has disappeared like a ghost without a trace.”

Authorities are making inquiries in Brazil, the US, and Europe as they hunt down Epstein’s co-conspirators.

French prosecutors are also pursuing claims relating to the Clinton-linked financier, who died aged 66 before he could face the latest allegations.

A friend of Bill Clinton and Prince Andrew, previously-convicted predator Epstein was found dead in jail on August 10 as he awaited trial on child sex trafficking charges.

According to the Daily Mail, Brunel - who founded New York’s MC2 - denies any involvement with crimes committed by Epstein.

A Paris legal source told the Daily Mirror: “He is a ghost who has disappeared without a trace.”

It comes after Russian former model Svetlana Pozhidaeva, who was signed to MC2, was pictured at convicted pedophile Epstein’s mansion in New York back in 2016.

Ms. Pozhidaeva, whose father is a Lieutenant Colonel in the Red Army, denies it is her in the picture.

Prince Andrew was photographed standing in the doorway of the same building the day before.

Virginia Roberts, who was a victim of Epstein’s, claims to have slept with Prince Andrew three times.

The Duke of York has vehemently denied that he slept with her and says he knew nothing about Epstein’s illegal behavior.

Roberts says she also slept with Brunel “many times” when she was aged 16 to 19.

Many of the girls believed to have been used by Epstein are alleged to have been “sourced” in Paris.

Epstein owned a £7million apartment in the French capital, where Brunel also lived.

The agency boss was searching for new talent in Brazil until the start of this summer.

This month, French prosecutors have started a preliminary inquiry into whether Epstein sexually abused minors from France.

They say Brunel is “uncontactable” because he has no address, internet accounts or social media.
