Jeffrey Epstein associate Ghislaine Maxwell was tracked down by the FBI using data from her mobile phone, a court document reveals.
Maxwell was arrested on 2 July during a raid on her secluded mansion in New Hampshire, reports the BBC.
She was located using global-positioning-system (GPS) data from a phone that had made calls to her lawyer, sister and husband.
Maxwell has pleaded not guilty to charges of trafficking minors.
Epstein died in a prison cell, in August 2019, awaiting trial on sex-trafficking charges, more than a decade after he was convicted for soliciting prostitution from a minor.
