The German Football Association have fined Bundesliga side Hamburger SV €55,000 (£42,200) after a pitch invader hit Bayern Munich winger Franck Ribery with a scarf.
The DFB said the pitch invasion during the game on 29 October, which ended 3-1 to Pep Guardiola's team, was caused by a security lapse. The fan also made a rude gesture at the French winger.
Hamburg were fined from offences at a range of matches this season, not just the Bayern clash, where supporters lit flares, threw lighters and used a high-pitch whistle that was "irritating".
"In the 60th minute of the home (league) game against Mainz 05 on 7 December, 2014, a whistle with an irritating sound was used several times from someone in the stands," the DFB said in a statement.
The former European champions, who accepted the fine, are struggling to avoid relegation for the second consecutive season, standing in 14th place, two points above Freiburg who are bottom.
The Bundesliga resumes on 30 January.
