The German second division club Dynamo Dresden have been fined €60,000 (£54,000) and will have parts of their stands closed for one game after their fans threw a severed bull’s head near the pitch during a Cup match.

The German football association (DFB) announced on Tuesday that repeat offenders Dynamo, who were already on probation following incidents last season, had failed to safeguard their high-risk German Cup game in August against RB Leipzig, who are nicknamed the Bulls.

Dresden fans had thrown a bull’s head on to the inside area of the stadium, unfurled insulting banners and hit one player with a coin during their win over their fellow eastern German club, owned by energy drinks maker Red Bull.

RB Leipzig’s seven-year rise into German football’s top flight has been dogged by boycotts and protest stunts by opposing fans. Unlike in other leagues in Europe, the statutes of the German Football Association deter big investors from taking over its clubs and many fans feel RB Leipzig have overstepped the mark in the deal with their sponsor.

There were a total of six incidents of unsportsmanlike behaviour from their fans, including at three other games in October, the DFB said, including the use of banned flares.

This is not the first time Dynamo has been sanctioned, with the club having been suspended from the German Cup in the 2013-14 season because of crowd trouble.
