Dortmund and Schalke hooligans clashed briefly at the Westfalenstadion after their Bundesliga match on Saturday.
After the final whistle, a group of Dortmund hooligans headed towards a section of the ground housing their Schalke rivals to attack them. Some Schalke hooligans, seeing this, immediately climbed over the fence separating the home and away sections and a fight started – but it did not last long. Riot cops quickly intervened and stopped the fight.
There were no reports of arrests.
