Arrest in bus attack probe as Borussia Dortmund lose rescheduled match

German authorities arrested a suspected Islamic extremist in their investigation into a bomb attack on Borussia Dortmund, while the team lost 3-2 to Monaco in a hastily rescheduled Champions League match.

Amid heightened security, the defeat in Europe's top club competition came less than 24 hours after three explosions shattered a window of the team's bus and rattled nerves across the city in western Germany.
