A federal judge on Tuesday denied bail for Ghislaine Maxwell, the British socialite accused of facilitating the sexual abuse of young girls in the mid-1990s by her former boyfriend Jeffrey Epstein, the now-dead investor.

Maxwell, who will remain in jail pending trial, pleaded not guilty at the bail hearing in Manhattan federal court, where her lawyer had sought her release on a $5 million bond.

Maxwell poses "a substantial risk of flight," said Judge Alison Nathan.

"The risk is simply too great" for Maxwell to be released on bail, Nathan said.

The judge noted Maxwell's wealth, citizenship in Britain and France, other international ties and lack of strong family or business connections in the United States as she denied the bail request. 

Nathan also cited the "seriousness" of Maxwell's alleged crimes as a reason she would have to flee and said no bail condition, or combination of conditions, would ensure she would willingly appear in court on the charges.

Maxwell, 58, faces up to 35 years in prison if convicted of crimes that include enticing minors into traveling to have sex with Epstein, and perjury.

The daughter of the dead crooked British media baron Robert Maxwell did not visibly react to the judge's decision, which she saw and listened to via a video teleconference from a Brooklyn, New York, federal jail.

The bail denial came nearly a year to the day after Epstein was himself denied bail on child sex trafficking charges after his lawyers offered to post a whopping $100 million bond.

A federal prosecutor who argued against Maxwell's bail request told Nathan that Maxwell had posed as "Jen Marshall," a "journalist" who was seeking privacy, last November when she looked at purchasing the New Hampshire house where she was found in her pajamas and arrested by FBI agents on the morning of July 2.
