Ghislaine Maxwell, known as a friend and former partner of late pedophile tycoon Jeffrey Epstein, is currently the focus of investigations by U.S. federal agents.

One of the sources familiar with the investigation told Reuters that British socialite Ghislaine Maxwell and others with ties to the American financier are being investigated by the FBI.

The FBI is also tracking down several women who have contacted a hotline set up by the intelligence agency in New York after Epstein’s capture in July.

Maxwell, “Manhattan media heiress,” is considered by federal authorities to be “the madam” and ” recruiter” who supplied underage girls to the sex trafficker, according to Fox News.

Epstein’s former partner, the daughter of the late Robert Maxwell, who owned several media outlets, was part of Epstein’s inner circle for years until she disappeared from public view in 2016, according to Reuters.

According to police sources, no details have been given about the other people associated with Maxwell and at this time they do not plan to interview Prince Andrew, who was accused of having sex with Virginia Roberts Giuffre.

Giuffre, who testified she was a victim of the tycoon’s pedophile network as a minor, recently declared via Twitter that she was not suicidal, implying that she or her family were possibly under threat.

“I am making it publicly known that in no way, shape or form am I sucidal,” she wrote on Twitter.

“If something happens to me—for the sake of my family do not let this go away and help me to protect them. Too many evil people want to see me quieted,” Giuffre added.

Giuffre filed a lawsuit against Maxwell after asserting that she had been his pimp, a claim that was rejected. According to the New York Post, Maxwell’s personal lawyers have not spoken about this case.
