Following Paris Saint-Germain's victory over Arsenal in the Champions League final, Paris police arrested over 130 individuals as they celebrated in the city. Thousands of officers were deployed to manage large crowds, particularly around the Parc de Princes stadium, where more than 40,000 fans gathered to watch the match on giant screens. Reports indicated that some fans engaged in violent behavior, including directing fireworks at police, leading to the use of teargas by law enforcement. The interior minister, Laurent Nuñez, emphasized the presence of a robust security system to maintain order during the festivities. Despite some clashes, many fans celebrated peacefully, with police estimating the crowd size on the Champs-Élysées boulevard at around 20,000. Authorities had heightened security measures following last year's incidents, which resulted in two deaths and nearly 200 injuries during similar celebrations.
