A 26-year-old man has given himself up and confessed to a mass knife attack at a street festival in Germany, police said on Sunday.
“The involvement of this person is currently under intensive investigation,” prosecutors and Düsseldorf police said.
He is under investigation for murder, attempted murder and membership of a foreign terrorist organisation, Germany’s federal prosecutor told the BBC.
Three people were killed and another eight injured in the city of Solingen during a festival to celebrate its 650-year history, in what Chancellor Olaf Scholz described as a “horrific act”.
The Islamic State group on Saturday claimed responsibility for the bloodshed, but did not immediately provide any evidence of a relationship with the attacker.
