The investigation is focused on two suspects from the "Islamist spectrum," spokeswoman Frauke Koehler said. Their homes have been searched and one has been temporarily detained, she said. Three explosive devices shattered windows and injured a player on the Borussia Dortmund team bus Tuesday evening local time as the German squad was en route to its home Champions League match against AS Monaco. Windows on Borussia Dortmund's bus were shattered by the blasts. Based on the type of detonator and explosive involved, German authorities assume "terrorist involvement" but the motives are unclear, Koehler said.
