Celebrations of Paris Saint-Germain's Champions League triumph spilled into violence across France overnight, with the interior ministry reporting 416 arrests nationwide — including 283 in the capital — after crowds that had gathered to mark the club's second consecutive European title clashed with police. Interior Minister Laurent Nuñez said seven officers were wounded in the disorder and called the scenes "absolutely unacceptable."

The trouble began in the hours after the final whistle in Budapest, where PSG beat Arsenal on penalties to retain the trophy. As fans poured onto the streets at home, the festivities curdled into confrontation in several cities. In Paris, an estimated 20,000 people massed around the Arc de Triomphe and along the Champs-Élysées, with some setting off flares, blaring car horns and lighting fires as riot police worked to contain the crowd.

Authorities reported damage to six vehicles and two businesses in the capital, and said a group of supporters broke onto the Boulevard Périphérique, the ring road that encircles Paris, halting traffic for a time as they set off flares on the carriageway. The disorder followed a now-familiar pattern from the club's recent European runs, in which mass street celebrations have repeatedly tipped into clashes and vandalism.

The French authorities had deployed thousands of officers in anticipation of large gatherings, mindful of disturbances that accompanied PSG's title run the previous season. The scale of the arrests pointed both to the size of the crowds and to a deliberate decision to intervene quickly against those throwing projectiles, looting or damaging property, rather than allowing the gatherings to run their course.

For the government, the unrest is an awkward postscript to a sporting achievement that should have been a moment of national celebration. PSG's victory made it only the second club in the modern history of the competition to retain the title, a milestone for French football, yet the morning's headlines were dominated by images of burning debris and lines of police rather than the trophy itself.

Officials indicated that those arrested would be processed in the coming days and that the response to the violence would be reviewed, with the interior ministry signalling little tolerance for a repeat. The episode renews a recurring debate in France over how to manage mass celebrations that have, with grim regularity, become flashpoints for confrontation between young crowds and the security forces sent to police them.
