AS Saint-Etienne, together with Paris Saint-Germain, are most champions in France and a classic football club.
Yesterday, the team left the top league for the first time in 18 years after a penalty loss at home against Auxerre at the Stade Geoffroy-Guichard in the negative qualifying game.
When the defeat was a fact, outraged home supporters stormed the pitch and threw projectiles and Bengals away towards the player tunnel where the players fled to escape the chaos.
Police and security guards tried to calm it all down, but up to 500 people went down on the inner floor.
According to the French newspaper Le figaro, 14 policemen and 17 supporters were injured.
In addition, three people will be taken to hospital.
On its website, AS Saint-Etienne condemns it all.
"Some were guilty of several acts of violence against players, security guards, the police and the public at the arena.
The ASSE strongly condemns these acts, gives its full support to the victims and will initiate the necessary legal proceedings ", they write in a statement.
