UEFA has announced it is to take action against Germany’s football association (DFB) over “improper conduct” by German fans during the win over Denmark on Sunday. The action means the DFB could be hit with a second fine in the space of a week.

UEFA said it was bringing the disciplinary action for the “display of inappropriate banners and symbols, and "inappropriate chanting,” but UEFA has not confirmed whether that had been racist in nature.

The DFB was also charged over fans setting off fireworks, and UEFA's Control and Disciplinary Body will deal with the case on Saturday.

The German association was fined €10,000 after fans threw balls of paper at Portugal players during their opening match.

The Football Against Racism in Europe (FARE) organisation, which has been working with UEFA to monitor crowd problems at Euro 2012, later announced one of its observers had reported a neo-Nazi banner in the German section of the crowd during the match in Lviv.

FARE posted on its official Twitter account: "FARE can confirm that one of our observers reported a neo-nazi banner in the German section at the match v Denmark in Lviv on Sunday."
