crowd incidents in the match St Etienne - Lyon

St Etienne 1 - 3 Lyon

The supporters of the two teams fight together with bengals, smoke-producing. The policemen used some "lacrimonège" gaz to calm the incident, and the match stopped during 20 minutes. Lyon and St Etienne are rivals because it was a derby and the fact that St Etienne was the leader of France in the 60's and 70's and now it's Lyon.
