A delayed kick-off, dangerous compact crowds, and tear gas. The Champions League final between Liverpool and Real Madrid on May 28 turned into chaos for fans and a nightmare for the government and the Union of European Football Associations (UEFA), the event's organizer. For Interior Minister Gérald Darmanin, the main reason for this fiasco was an "industrial-scale false ticket fraud." What really happened? Our investigation reveals that the presence of supporters without tickets or with fake tickets was real on May 28, and even expected by the French authorities. But it was not the cause for the incidents that occurred around the stadium. Thanks to hundreds of photos and videos of the events published on social media, Le Monde's video investigation department was able to reconstruct the timeline and the routes taken by the thousands of supporters that evening. The documents were shot as close as possible to the events and shed light on the erratic crowd control measures and the inadequate policing around the stadium.
