Cologne and Borussia Monchengladbach fans clashed in the stands during their Bundesliga clash on Sunday.
The violence erupted after Cologne took a 2-1 lead in the 67th minute at the RheinEnergie Stadium. Rival fans traded punches and attacked each other with belts in the upper tier of the stands after Gladbach fans damaged the glass barrier separating the home and away sections.
Police intervened after several minutes, prompting the referee to briefly suspend the match. Play resumed after order was restored.
