Paris Saint-Germain clinched their second UEFA Champions League crown Saturday night, edging Arsenal on penalties in Budapest. The dramatic shootout sparked a city‑wide party as thousands streamed onto the Champs‑Élysées, blaring horns and lighting flares. Fans gathered near the Arc de Triomphe and the Parc des Princes, eager to revel in the historic triumph, waving scarves and singing the club anthem.

Police intervened after smaller groups turned festive crowds violent, vandalising shops in several districts and igniting fires. Officers dispersed a mob that tried to breach a precinct in the upscale 8th arrondissement and cleared a bicycle barricade near the stadium. By 10 p.m. officials confirmed 45 people were taken into custody, and one officer sustained injuries, including a handful of arrests near the bakery.

The unrest echoes last May, when more than 500 arrests followed PSG’s first European triumph and the city deployed 8,000 officers. Authorities now face the challenge of balancing celebration with public safety in a capital accustomed to large‑scale gatherings throughout the city. Paris police say they will maintain heightened patrols around the stadium for the remainder of the week.
