Numerous people were injured, some seriously, in what police have described as an "extremely violent attack" by some Bayern Munich and Bochum fans who attempted to storm a cash desk at Schalke's stadium on Saturday. Gelsenkirchen police say in a statement "only a swift and consequent intervention by police forces prevented worse. Several dozen from this violent group of people are being held." Bayern chairman Karl-Heinz Rummenigge says the club distances itself "in every form from these so-called supporters of our club." Rummenigge adds "violence cannot and should not ever be tolerated. It's absolutely inexplicable to me and to all of us how someone, especially now after the terrible events in Paris, can be so lacking in respect for society and football." Rummenigge also apologized to Schalke and the victims.
