A few hours before the second leg of the UEFA Champions League semi-final between Bayern Munich and Paris Saint-Germain, there was a security tension among the fans of both clubs at the metro stations (U-Bahn) in the city of Munich.

According to field reports, altercations broke out between some Paris Saint-Germain and Bayern Munich fans as they made their way to the Allianz Arena, leading to chaos inside one of the train cars.

Reports indicated that Paris fans were pursued inside the train before being evacuated later due to the spread of thick smoke in the area, which necessitated an urgent intervention by the authorities.

The police also asked a group of Paris Saint-Germain ultras to leave the station in an attempt to control the situation and contain the tension before the anticipated match.
