Violence mars Borussia Dortmund's Bundesliga defeat by Schalke.
• German police arrest 200 people during rioting at derby
• Fans are escorted from stadium in a huge police operation
Borussia Dortmund's 2-1 defeat by Schalke was marred by violence. Police arrested 200 people and eight officers were injured while water cannon were used to prevent Schalke fans from pulling down a fence before the start of the Bundesliga derby match
Fans were escorted from the stadium in a huge police operation employing around 1,000 officers.
According to police reports, a restaurant was gutted by Dortmund followers "with furniture ripped apart and used as missiles against opposition fans and police".
One police car was damaged as mounted police, riot police and dogs were brought in to keep rival fans apart.
Hours before the game kicked off at 3.30pm local time, followers of both clubs attacked police who tried to segregate them in the Westphalian city and water cannons and tear gas had to be deployed to keep them at a safe distance.
Mounted officers were "attacked by Dortmund hooligans with cobble stones", according to police reports.
Schalke's manager, Horst Heldt, was shocked by the rioting. "That's not what we imagined happening here," he said. "Before the game, both clubs had made a statement that we hope the rivalry would be contained to the pitch. This is not nice and can't be accepted. Maybe at some point, we can express emotions through chanting and cheering."
Dortmund's police chief, Dieter Keil, said: "This has nothing to do with the enthusiasm for football and has nothing to do with what we want to see in Dortmund."
