The Berlin senate administration is to investigate the incidents at the German Cup final last week following massive accusations from Arminia Bielefeld fans over poorly organized admission controls at the game.

However, the authority sees the German Football Federation (DFB) as responsible for the potentially dangerous events.

“As the organizer of the German Cup final, the DFB is responsible for the security concept,” the senate administration said in a statement.

“Allegations that there were issues during this year’s German Cup final are being evaluated by the Olympiastadion Berlin GmbH and the DFB.”

Third-division side Bielefeld played their first-ever Cup final last Saturday in Berlin’s Olympic stadium against VfB Stuttgart, but were defeated 4-2.

Several Bielefeld supporters complained about the chaotic conditions in front of the entrance gates dedicated to them.

Thousands of fans had to wait for hours to be admitted and had to stand tightly packed in front of the gates without being able to leave.

A possible mass panic among the fans was only avoided by their common sense and luck, they said.

Bielefeld said of the situation: “It is incomprehensible to us and in no way acceptable that such serious inconveniences occurred at the most important match in the club’s history and one of the biggest events in German professional football.”

The DFB had already apologized for the issues, expressed its dismay and announced that it would investigate the matter.

There were no complaints from Stuttgart fans, who had a different dedicated entrance.

The German Cup final has been held in Berlin’s Olympic stadium since 1985. This year’s match was sold out with 74,036 spectators.
