German police believe the incident was a targeted attack on the Dortmund team and a suspect with "Islamist links" has been detained.
A spokeswoman for Germany's federal prosecutor, Frauke Koehler, said: "Two suspects from the Islamist spectrum have become the focus of our investigation. Both of their apartments were searched, and one of the two has been detained."

Dortmund goalkeeper Roman Burki was sat next to Bartra and described the moment when the explosions hit.
He said: "The bus turned on the main road when there was suddenly a huge bang – a proper explosion.
"The police were quickly on the spot and handled the situation. We were all in shock and no one was thinking about football anymore.
"I was sat next to Marc Bartra on the back row of the coach and he was injured because of the broken window.
"After the bang, we all ducked and those who could lay on the floor did so. We didn't know what else would happen."
