New claim over Dortmund attack linked to far-right
German investigators are examining a third possible claim of responsibility for the attack on Borussia Dortmund's team bus - this one containing far-right rhetoric.
Berlin's Tagesspiegel daily reported that it received an email on Thursday evening in which the anonymous author mentions Adolf Hitler, rails against "multiculturalism" and says the Dortmund attack was a "final warning".
Federal prosecutors confirmed that they received the mail from the newspaper.
Three explosions shattered a window on Dortmund's bus on Tuesday ahead of the team's Champions League match against Monaco. One of Dortmund's players, the defender Marc Bartra, and a police officer were wounded.
Three copies of a note containing Islamic extremist rhetoric were found at the scene, but officials have raised the possibility it might be a red herring.
Prosecutors have questioned the credibility of another claim posted online, suggesting a left-wing extremist motive.
