Two people have died and 192 have been injured after chaotic scenes following PSG's Champions League win over Inter Milan last night.
Police made 426 arrests in the French capital as the celebrations descended into chaos.
A 17-year-old boy was stabbed in the chest, and a 20-year-old woman was hit by a vehicle carrying supporters, per reports in France.
As early as half-time, police used water cannons at the Champs-Élysées.
According to police it was to "protect the Place de l'Étoile, as the barrier set up had been broken through by a large crowd of people not watching the match, pushing to come into contact with the police."
Footage shared on social media showed supporters clashing with police armed with batons.
Between 2,000 and 3,000 people had gathered on the Champs-Élysées alone.
France's Interior Minister Bruno Retailleau said on social media: "True PSG fans are getting excited about their team's magnificent performance.
"Meanwhile, barbarians have taken to the streets of Paris to commit crimes and provoke law enforcement. I have asked the internal security forces to react vigorously to these abuses.
"I offer my support to the Police Prefect and all the police officers who are ensuring everyone's safety this evening.
"It is unbearable that it is not possible to party without fearing the savagery of a minority of thugs who respect nothing."
