UPDATE: The Real Deal misidentified the source of this information, and they've issued a statement to that effect. The information instead came from the Offshore Leaks database also published by the International Consortium of Investigative Journalists (ICJI).

The release of the Panama Papers, a leak of millions of files from the offshore law firm Mossack Fonseca, has already led to the resignation of Iceland's Prime Minister, and has revealed the secretive offshore dealings of the likes of Russian President Vladmir Putin, and the Pakistani premier, Nawaz Sharif. Prior to that, The Real Deal's analyzed another set of documents released by the ICJI that revealed at least five firms with NYC connections.

They are: Stonehenge Partners, the Witkoff Group, one of the co-owners of Hiro Real Estate, M1 Real Estate, and members of the Nakash Family, one of whom is an investor in the New York Wheel project.

Witkoff's most notable projects include the 91-unit West Village condo building at 150 Charles Street, the Helmsley Park Lane Hotel, the Woolworth Building, and the 24-story, 10 Madison Square West. Stonehenge Partners manages over 3,000 apartments across the city, according to TRD.

The Panama Papers leak came about when an anonymous source provided the data to German newspaper Süddeutsche Zeitung a couple of years ago. The paper in turn shared that information with the International Consortium of Investigative Journalists (ICJI), which then subsequently provided that information to several large publications.
