A German police investigation into who carried out the bomb attack on the Borussia Dortmund football team's bus is reportedly focusing on both Islamic extremists and anti-fascist groups.

Officials said a letter was found near the scene and that two suspects were sought, one of whom was detained.

German Chancellor Angela Merkel has condemned the attack on the Bundesliga team as "repugnant" as the investigation continues.
