FBI used phone ‘ stingray’ device to find Maxwell

Ghislaine Maxwell was tracked down by the FBI to a secluded New Hampshire hideaway using a controversial “stingray” device that intercepted GPS data from her mobile phone.

The 59- year- old British socialite, pictured, is accused of helping traffic underage girls for the late financier Jeffrey Epstein.

The FBI filed an affidavit in support of an application for a search warrant a day before her July 2 arrest.

The agency wanted access to GPS and historical mobile data for Maxwell’s phone account, which had a northeastern Massachusetts postcode — within one square mile of her location.

However, they could not ascertain which exact house in the Bradford area of New Hampshire she was staying and requested a further warrant to use a “stingray” device, also known as an “IMSI catcher.”
