A 27-year-old man has been sentenced to two months in prison, plus a further two months suspended, after being found guilty of throwing glass bottles at police during the violence that marred Paris Saint-Germain's Ligue 1 title celebrations in the capital on Monday.
Prosecutors had wanted a longer sentence to be handed down to the unemployed man, named only as Mickael and living with his parents in Paris' upmarket 8th arrondissement, who is the first to be sentenced following the trouble.
The man, who was still wearing a replica PSG shirt in court, described himself as having been "a supporter of the club since a young age" and said he had arranged to meet with friends at Paris' Place du Trocadero, where PSG received the Ligue 1 championship trophy.
The man, who has a previous conviction for robbery, had protested his innocence.
Eleven other men, mostly in their 20s, also appeared in court in Paris on Wednesday, while PSG earlier called off a dinner to be held for their charitable foundation due to the violence in the capital at their title celebrations.
PSG had been planning a dinner at the Town Hall with Mayor of Paris Bertrand Delanoe but the fall-out from the violence and destruction that accompanied their title party in the Trocadero neighbourhood saw it postponed.
"Following Monday's incidents in Paris, (president) Mr (Nasser) Al-Khelaifi has decided to push back this event to a later date," said a club statement.
A group of fans had fought running battles with police, smashed shop windows and set cars on fire during the incidents on Monday.
Several people were injured and a total of 47 people have been arrested over the trouble.
PSG had sealed their first title in 19 years with a 1-0 win at Lyon on Sunday.
