Borussia Monchengladbach have said they are horrified after a woman was sexually abused on a train as fans travelled back from the defeat at Bayern Munich.
A privately chartered train with 750 Gladbach supporters on board was stopped by police in Hesse after the 19-year-old woman called for help after being assaulted in a toilet.
The woman was taken to hospital after talking to officers, who have identified a suspect, the club said on Sunday.
"This is a horrible incident and we condemn it," Gladbach executive Stephan Schippers said in a statement on the club's website.
"We hope the perpetrator can be identified and brought to justice. It's a disgrace that Borussia is connected with such a deed."
