Because of a suspicious vehicle on the stadium forecourt, the 81,365 spectators of the top Bundesliga game between Borussia Dortmund and Bayer Leverkusen (1-0) were not allowed to leave the stadium immediately after the final whistle.
In the arena on Saturday evening, from five minutes before the end of the game, it was announced several times that “due to a police operation outside the stadium” all fans must remain on their seats.
The situation only slowly cleared up half an hour after the final whistle and the fans were allowed to leave the arena with a delay.
“Please behave calmly and follow the instructions of the security forces,” tweeted the Dortmund police. The officials previously said: “A suspicious vehicle with the engine running has been found in the area of Parking E3.”
At that point in time, “it could not be ruled out” that “this vehicle could pose a threat.” The spectators were initially not allowed to leave the stadium, “so that the police measures can be carried out undisturbed.”
