PSG and Zagreb fans clash in Paris
Fans of Paris Saint-Germain and Champions League opponents Dinamo Zagreb have clashed in the French capital, with police arresting 24 people after late-night disturbances.
The violence took place in the Place de la Bastille at around midnight on Monday. Police said one supporter of the Croatian champions was badly injured.
On Tuesday, French police said they had arrested around 80 Dinamo Zagreb fans at a hotel in the city as they attempted to avert the threat of further violence on the day of the match.
The developments happened after Manuel Valls, the French interior minister, had imposed a travel ban on Zagreb fans, saying he hoped the measure would "avoid serious security risks to people and property".
Valls told reporters Croatian police had informed their French counterparts that around 200 violent members of the Blue Bad Boys gang would be travelling to France without tickets for the Parc des Princes.
A French police spokesman said: "Clashes erupted between PSG and Dinamo Zagreb fans in the Bastille area. Police were sent to end the brawl.
"Some, mostly Croatians, were arrested, and others detained for questioning. One Croatian was severely injured."
The two teams meet on Tuesday night, with PSG - who lost their first Ligue 1 match of the season to St Etienne at the weekend - looking to keep the pressure on group leaders Porto.
Carlo Ancelotti's side beat Zagreb 2-0 in Croatia a fortnight ago, and will be heavily backed to repeat that result against opponents who have yet to score a goal in the Champions League.
