Ghislaine Maxwell barricaded herself in prison conference room

Ghislaine Maxwell used a cart full of legal documents to “barricade” herself inside a conference room at a Brooklyn lockup, causing a “security threat,” prosecutors have alleged.

Maxwell — Jeffrey Epstein’s alleged madam — has been allowed to meet with her lawyers in a virtual teleconference room at the Metropolitan Detention Center ahead of her trial on charges that she groomed underage rape victims for the dead pedophile.

But at one of the meetings, Maxwell used a cart to hold legal documents “to barricade the door to the VTC room, thereby preventing MDC staff from being able to access the room,” Manhattan federal prosecutors alleged in a letter to a judge Monday.

“Because of the security threat posed … the defendant is no longer permitted to bring the cart into the room,” the letter continued, noting that Maxwell can now only take in what she can carry for the hours-long, weekday meetings.

The 59-year-old British socialite’s lawyer, Bobbi Sternheim, fired back in a letter Tuesday accusing prosecutors of being unable to “resist the opportunity to gratuitously cast Ghislaine Maxwell in a negative light while it defends the Metropolitan Detention Center at all costs, regardless of the facts.”

Sternheim denied that his client used the cart to block access to the room and claimed that the prosecutors made it an issue “when it never was — to justify the restriction placed on the amount of legal materials Ms. Maxwell can bring into the VTC room on any given day,” the letter said.

Sternheim further claimed that the rules constantly change on what legal materials Maxwell can access depending on the rotation of guards — which affects the defense’s productivity “and compromises Ms. Maxwell’s ability to prepare for trial.”

Manhattan federal Judge Alison Nathan told Maxwell’s lawyers to notify the court if they have any issues communicating with their client.

But in the meantime, “The court remains confident that Ms. Maxwell is fully able to communicate with her defense counsel and to prepare for trial,” Nathan wrote in an order from Wednesday.

Maxwell pleaded not guilty to an eight-count indictment including sex-trafficking charges. If convicted at trial — which is set for late November — she faces up to 80 years behind bars.
