people were arrested across the country. Officers reported also two deaths, a man hit by a car while riding a scooter in Paris and a 17-year-old stabbed during the celebrations in the southwestern town of Dax, although the prosecutor's office has declared it's not clear yet if the episode of violence was related to Champions League celebrations.
The title is tethering on misinformation, it's most likely "just" incidents that happened in France on that day, not the PSG fans turning violent.
