Investigators in Germany say there is “significant doubt” that Tuesday’s attack on the Borussia Dortmund team bus was the work of radical Islamists.
They say letters found at the scene may be an attempt to trick people into thinking there was an Islamist motive.
But they said it may have been the work of political extremists – from the left or right – or violent football fans.
…
Investigators were still not clear about what kind of attacker might have wished to frame Islamists for an attack, but said the explosives used in the attack were professionally-made.
And another German newspaper, Tagesspiegel, said it had received an email from someone with right-wing motives, who said the attack was a warning and made racist threats.
The authorities are taking that email seriously, the newspaper reported.
