Hans-Joachim Watzke has stressed Borussia Dortmund will come down hard on the fans who attacked RB Leipzig supporters on Saturday.

Borussia Dortmund chief executive Hans-Joachim Watzke has vowed to punish the fans who were involved in the violent scenes before Saturday's Bundesliga win over RB Leipzig.

German police arrested 28 people relating to attacks on visiting fans before this weekend's match.

According to local police, some RB Leipzig fans were pelted with various missiles including bottles and stones as they made their way to Signal Iduna Park, with violence also directed towards children and families.

Arrests were made for assault, grievous bodily harm, breach of the peace and resisting arrest and Watzke has made it clear Dortmund will do everything within their powers to prevent a repeat.

"Now two days after the events during the match against RB Leipzig we are still in shock over the level of violence and insults that took place," a statement from Watzke read.
