Two fans died and a police officer is in a coma after celebrations for Paris-Saint Germain's historic Champions League victory, European soccer's biggest prize, authorities say.

“Paris Saint-Germain condemns in the strongest possible terms the violence that occurred during the celebrations,” PSG wrote on social media on Sunday afternoon, with their players having flown back to Paris from Munich with the Champions League trophy ahead of their open-top bus parade.

Some 491 arrests in Paris have been made while police confirmed a 23-year-old man was killed after being hit by a vehicle in the city.
