German police have arrested 21 Galatasaray fans following trouble during their clash at Borussia Dortmund.
The Champions League Group D game at Signal Iduna Park was stopped twice as firecrackers were thrown onto the pitch from a section of away fans - leading to several Galatasaray players remonstrating with their own supporters.
Police detained and checked the identities of over 700 Galatasaray fans and arrested 21, also opening an attempted manslaughter case as part of the same investigations.
"The police have made it very clear that we will show consistent law enforcement," said police chief Gregor Lange at a press conference on Wednesday.
"We have to question whether the police were showed due respect in a very difficult situation. Lives were at risk."
The Turkish visitors, who were fined £40,000 for throwing flares at Arsenal earlier in the group stages, lost the game 4-1.
Dortmund manager Jurgen Klopp said of the violence, which saw 250 of the stadium's seats destroyed: "This is frustrating and a bad image. It casts a bit of a shadow over an otherwise great game."
