DORTMUND, Germany (AP) -Bitter German rivals Borussia Dortmund and Schalke have issued a joint condemnation of rioting before this past weekend's Bundesliga match between the clubs.
About 200 people were detained following the violence ahead of Saturday's derby between defending champion Dortmund and local rival Schalke.
The clubs said in a joint statement Monday that the a few hundred violent supporters "abused" the match and "knowingly endangered the safety of the overwhelmingly peaceful majority of fans and the security forces."
The two clubs say they will analyze the weekend's events along with police. Schalke security chief Volker Fuerderer says they have a "responsibility to consider new conceptual approaches."
Schalke won the match in Dortmund 2-1.
