Borussia Dortmund have banned the fans who displayed a homophobic banner at a recent home match from the stadium for three years.
The banner was displayed during Dortmund's 1-0 win over Werder Bremen on March 17.
A statement on the club's official website read: "After discussions with the Ultra group, which was responsible for the offensive and homophobic banner that was displayed on the South Tribune of Signal Iduna Park at the game against Werder Bremen, Borussia Dortmund have given the people who were responsible for the action the maximum penalty of a three-year stadium ban."
The club added the Ultra group had a "very intensive discussion" with Dortmund chief executive Hans-Joachim Watzke during which they apologised publicly for the incident.
Watzke said: "In this discussion we made it very clear that Borussia Dortmund stands for tolerance, openness and respectful behaviour towards everyone."
