A man armed with a four-inch knife killed one person and wounded at least three others at a train station near Munich, Germany, early Tuesday, officials said.
A 27-year-old German national was arrested shortly after the attack in the suburb of Grafing. Witnesses told police the suspect was shouting "Allahu Akbar" — which means "God is great" in Arabic — but authorities later said he had no known connection to a terror group.
Bavaria's interior minister, Joachim Herrmann, said the suspect had recently been stopped by police in another part of Germany because of his behavior and on suspicion of drug use. He added that the suspect did not appear in any database of Islamists or ISIS sympathizers.
