Just after midnight an altercation between the two sides escalated into a massive fight involving teenagers and young adults near the club. Police estimated there between 250 and 300 young people involved.
"As the first patrol cars arrived the young people scattered in all directions," a police statement said.
But police were able to detain some well known violent offenders at the scene. A short while later more fights were reported and police questioned some 50 rowdies nearby.
The rumble resulted in at least three dangerous injuries, police said. Other people suffered knife wounds and broken noses.
Authorities took five underage ruffians between the ages of 16 and 19 into custody and returned them to their parents. All of those arrested were under the influence of alcohol, police reported.
Fürth police inspectors are investigating the event using video surveillance of the area.
