Bayern Munich has been fined $19,800 by the German Football Association (DFB) following a series of crowd incidents during recent Bundesliga matches.
The DFB said it was acting against the league leader "because of two cases of unsporting behaviour and not having enough stewards."
Bayern fans set off flares during a clash with Fortuna Dusseldorf at the Allianz Arena on October 20, while fireworks were let off during the November 17 clash with Nurnberg.
The club's stewarding procedures were then called into question when a Bayern supporter tried to gain access to the pitch during the match with Borussia Dortmund on December 1.
Bayern informed the DFB the club has accepted the ruling.
