The troubles begun on the stadium when FC Zurich fans jumped over the fence of the away sector to enter the home sector and attacked FC Luzern fans.
After the match different fights in the city.
The agressive mood of FC Zurich fans was a reaction on what happened in Luzern at 16th August 2014 when Luzern supporters attacked busses with FCZ fans with stones. Then fights started when FCZ fans came out of the busses. Yesterday three FCL and two FCZ hooligans have been charged with high sentences for the riots at 16th of August 2014.
