Violent clashes erupted in Paris and other French cities on Saturday night following Paris Saint-Germain's (PSG) victory over Arsenal in the Champions League final. French police detained a total of 780 individuals in connection with these disturbances, with 480 detentions occurring in the Paris area alone. Interior Minister Laurent Nuñez reported that 57 officers sustained injuries, mostly minor, amidst the chaos where football fans set fires, vandalized shops, and engaged in various acts of disorder.

While Nuñez stated that the situation was largely brought under control by Sunday, and that the majority of celebrations across the French capital were peaceful, significant incidents concentrated around the Champs-Élysées and near the Parc des Princes stadium in western Paris, where fans had gathered to watch the match on giant screens. Incidents were also reported in approximately 15 other French cities, with minor vandalism in one to two shops per city.

The Paris prosecutors’ office confirmed that 277 people, including 82 minors, were formally placed in police custody for alleged offenses such as assaulting police officers, theft, vandalism, and disturbing public order. A particularly serious incident involved a driver losing control of a car, ramming into a restaurant’s terrace and injuring two people, one seriously.

Despite the overnight violence, planned celebrations for the team's win on Sunday afternoon at the Champ de Mars, near the Eiffel Tower, were set to proceed as scheduled. Following this, the PSG team was slated to be hosted by French President Emmanuel Macron at the Élysée Palace. Footage from news channels depicted brief skirmishes around PSG's Parc des Princes stadium, where over 40,000 people watched the club secure its second consecutive title on penalties from the Puskas Arena in Budapest.

By 11 pm local time, police had already made more than 130 arrests. Reports indicated that some PSG fans directed fireworks at police officers, who responded with teargas. Some fans were seen wearing provocative T-shirts and standing near burning Lime bikes amidst rising smoke during the clashes. Police, equipped with riot gear, were seen pursuing groups of fans and extinguishing flares. France had deployed 22,000 police officers to maintain order in the capital, reminiscent of incidents the previous year when PSG's first Champions League win resulted in two deaths and nearly 200 injuries. The Champs-Élysées, partly cordoned off, saw a crowd of an estimated 20,000 mostly peaceful PSG fans, though smaller groups caused disturbances, vandalized shops, set fires, and even attempted to storm a police station in the upmarket 8th arrondissement before being dispersed.
