According to Bild newspaper, 23-year-old goalie Tobias Sippel and midfielders Thanos Petsos, 20, and Ivo Ilicevic, 24 – all members of Kaiserslautern's first team – went partying Sunday in the city's historic district.
They then drove a BMW to a nearby brothel, but allegedly hit a parked car as they arrived. After a resident notified the police, the players were apprehended by officers in the red-light establishment, the newspaper reported.
Kaiserslautern Chief Prosecutor Paul Scheidner confirmed the incident occurred but told Bild it was not clear who had been driving the car.
However, Sippel was forced to submit his drivers licence immediately to the police.
Club boss Stefan Kuntz is reported to be extremely upset at his players and talked to them about the situation during practice on Tuesday.
In a statement to Bild the club said it was aware of the situation but declined further comment.
