FBI agents had to break down a door to arrest Ghislaine Maxwell, who had wrapped a mobile phone in tin foil to avoid detection, prosecutors say.
The former associate of convicted paedophile Jeffrey Epstein was being guarded at her home by former members of the British military when she was arrested on 2 July, New York court papers also said.
Ms Maxwell faces up to 35 years in jail over allegations she recruited teenage girls for Epstein to sexually abuse in the 1990s.
Lawyers said the socialite, 58, is an “extraordinary” flight risk as she has British, French and US passports and is “skilled at living in hiding”.
Revealing details of her arrest at the New Hampshire estate she purchased in December, prosecutors said FBI agents told Maxwell to open the door but she refused.
“Through a window, the agents saw the defendant ignore the direction to open the door and, instead, try to flee to another room in the house, quickly shutting a door behind her,” they said.
Agents were forced to break through the door to arrest Maxwell.

During a security sweep of the house agents found a mobile phone wrapped in tin foil on a desk which they said was “a seemingly misguided effort to evade detection, not by the press or public, which of course would have no ability to trace her phone or intercept her communications, but by law enforcement”.
The only other person at the property at the time of Maxwell’s arrest was a private security guard who told the FBI Maxwell’s “brother had hired a security company staffed with former members of the British military to guard the defendant” at the house on rotation, the court filing said.
It also emerged that at least one of Epstein’s victims, and possibly more, will tell a judge at a hearing on Tuesday that Ms Maxwell should be denied bail.
Her lawyers will argue she should be released on $5m (£3.9m) bail with electronic monitoring as they said she is being made a scapegoat after Epstein killed himself in jail last August.
Prosecutors allege Maxwell played a central role in facilitating Epstein’s crimes and she contributed to “sexual exploitation that caused deep and lasting harm to vulnerable victims”.
Maxwell last week said she “vigorously denies the charges” and intends to fight them, her lawyers also argue that she is protected by a plea agreement Epstein struck in 2007 in Miami, which covered “any potential co-conspirators.”
