As far as the French justice system is concerned, Arnaud Mimran is one of the “organisers” of what has been dubbed the hold-up of the century: the massive carbon trading fraud that cost French taxpayers around 1.6 billion euros in 2008 and 2009. The French businessman is suspected, too, of being behind the kidnapping of a Swiss financier in 2015 in a bid to extort 2.2 million dollars. The 44-year-old poker player's name has also been cited in connection with several unsolved murders, including that of his former father-in-law.
