Ghislaine Maxwell Tried to Hide When F.B.I. Knocked, Prosecutors Say

After her arrest, a private security guard who worked on the property told the F.B.I. that Ms. Maxwell’s brother had hired former British military members to protect her in New Hampshire, the prosecutors said in their filing Monday.

The guard told the agents that he was given a credit card in the same name as the L.L.C. to make purchases on Ms. Maxwell’s behalf, and said that Ms. Maxwell did not leave the property at all during his time there, according to prosecutors.

The government has asked the judge, Alison J. Nathan of Federal District Court, to deny Ms. Maxwell bail. She had changed her email address, they said, and registered a new phone number under the name “G Max.”

The prosecutors have argued that she posed an “extreme risk of flight” because of her financial resources and other factors. She had passports from three countries, and investigators said they had identified more than 15 bank accounts linked to her, the total balance of which at times exceeded $20 million.

Between 2007 and 2011, the prosecutors had said, more than $20 million was moved from accounts associated with Mr. Epstein to accounts associated with Ms. Maxwell, who once was a fixture on New York’s social scene. The government called her total financial picture “opaque and indeterminate.”

In Ms. Maxwell’s bail motion last week, her lawyers tried to distance her from Mr. Epstein.

They denied that she posed a flight risk and asked Judge Nathan to release her into home confinement on a $5 million bond.

“Ghislaine Maxwell is not Jeffrey Epstein,” her lawyers wrote.

Ms. Maxwell’s arrest came one year after Mr. Epstein was charged with sexually exploiting and abusing girls and young women at his mansion in Manhattan and other locations. Audrey Strauss, the acting U.S. attorney in Manhattan, said that Ms. Maxwell had “enticed minor girls, got them to trust her, then delivered them into the trap that she and Epstein had set for them.”
