The RB Leipzig fan train was attacked by unknown persons before the return journey from the game at Borussia Mönchengladbach. There was talk of a butyric acid attack on social media. The federal police told dpa that a foul-smelling liquid had escaped from broken bottles in two carriages. No one was injured.
The Federal Police did not confirm that the liquid was butyric acid, but the assumption is reasonable. The same applies to the assumption that the unknown perpetrators were Gladbach supporters. The train was blocked by the federal police and the return journey was delayed. At the time of the attack, the 600 fans were still on their way from the stadium to the train after the 0:1 defeat.
