European football's governing body will investigate a further two instances of wrongdoing by the German champions and their fans, including a delayed kick-off time
Uefa has opened disciplinary proceedings against Bayern Munich over an 'illicit' banner displayed by fans during their clash with Arsenal on Tuesday.
The banner, which depicted a cannon, Arsenal club record signing Mesut Ozil and the words "Gay Gunners", was highlighted by the media and spread across Twitter
following the 1-1 draw at the Allianz Arena.
The proceedings will also investigate "discriminatory behaviour" of the Bayern fans, as well as a delayed kick-off time.
Uefa say the case will be heard on March 20 by the Control and Disciplinary Body.
Arsenal drew 1-1 on the night but lost 3-1 on aggregate and were knocked out of the Chamions League at the last-16 stage.
Bastian Schweinsteiger scored for the hosts before Lukas Podolski, a former Bayern player, equalised for Arsene Wenger's side.
