Police made 205 arrests on Friday evening as fans of Borussia Monchengladbach and Cologne clashed before Saturday’s Rhine derby.
Police said 131 Cologne fans and 74 Monchengladbach supporters were taken into custody after violence erupted outside Borussia Park.
Fans from home side Monchengladbach had been at the ground the day before the match to prepare a crowd display.
Three police officers were injured during the clashes at about 21:00 CET.
“The police forces on site were able to prevent further confrontation between the two groups and separate the problem fans,” said Monchengladbach Police.
