BERLIN Germany's federal prosecutors' office said on Tuesday that they had not found any indications that there was a "terrorist background" to the attack on the Borussia Dortmund soccer team bus on April 11.
"Investigations carried out up until now have not given us any clues that there was a terrorist background to the attack," prosecutors said in a statement.
Letters left at the scene had suggested Islamist militants were behind the bomb attack.
Prosecutors said they believed suspect Sergei V., a German-Russian dual national who was arrested on April 21, carried out the attack "purely for monetary reasons".
