In the latest uncovered emails buried within the millions of Epstein files, they confirm for the first time that he made covert recordings across his property portfolio, according to The Telegraph. The video shows a desk chair with a large bookshelf behind it. Someone can be seen walking past the camera. The setting appears to be a working area with a white desk and chair visible.

Epstein ordered his pilot, Larry Visoski, to buy “three motion-detected hidden cameras that record”. The hidden cameras were installed in Kleenex boxes.

Mr Visoski, who also worked as a technician and general handyman, replied, confirming that he had already purchased the surveillance equipment and started “installing them in Kleenex boxes now”.

In an email dated February 5, 2014, Mr Visoski told Epstein that he had bought the cameras from a Fort Lauderdale spy shop the day before and was “figuring out how they work as we speak.”

On the same day the hidden cameras were brought, the disgraced financier received an email from someone else, whose name is redacted, saying: “Remember what we spoke about if you want to put cameras in the house. It will have to be very discreetly done. The Russians may come in handy.”

The email exchanges about the hidden cameras contain no further reference to Russians.

It has been alleged that Epstein may have been cooperating with Russian intelligence, gathering so-called “kompromat” — compromising material — that could be used to blackmail, discredit or exert influence over wealthy and high-profile individuals.
