German authorities conducted multiple large-scale police operations targeting football supporters across the country's rail network over the weekend, resulting in numerous detentions and temporary service disruptions. The incidents occurred as fans traveled to Bundesliga matches, with law enforcement intervening following reports of altercations between rival supporters and attacks on police personnel.

In Baden-Württemberg, approximately 70 TSG 1899 Hoffenheim supporters saw their away trip to face SC Freiburg end prematurely after their regional train was stopped at Herbolzheim station. According to police statements, the intervention followed provocations between Hoffenheim and Freiburg fans aboard the train, prompting federal police to escort the service. The situation escalated when some Hoffenheim supporters allegedly insulted and physically assaulted the accompanying officers.

Simultaneously in Berlin, police mobilized multiple response vehicles at Jannowitzbrücke station ahead of 1. FC Union Berlin's match against Hamburger SV. Officers entered the station and controlled approximately 200 Union supporters on suspicion of breach of the peace and bodily harm. The operation caused temporary suspensions of S-Bahn lines S3, S5, and S7, with service resuming around 6 PM amid ongoing delays and cancellations.

The coordinated police actions reflect heightened security measures surrounding German football fixtures, particularly concerning fan transportation. While the Freiburg versus Hoffenheim match proceeded as scheduled at 3:30 PM without the detained supporters, the incidents underscore ongoing challenges authorities face in managing fan behavior on public transport systems during major sporting events.
