A 19-year-old man was arrested in Vienna after he allegedly threatened passers-by with a folding knife. Police were called on 19.10.2026 at around 22:00 from Wien-Leopoldstadt after the man reportedly confronted people with the blade. Officers from the Polizeiinspektion Ausstellungsstraße stopped a suspect nearby. Witnesses led them to a folding knife that the man had allegedly thrown away near the scene. When police confronted him, the 19-year-old behaved aggressively and refused to cooperate. He allegedly insulted the officers and threatened to punch them. One of the people targeted, an 18-year-old, told police the pair had been smoking outside his home with his mother when the suspect suddenly began to pester them. The 19-year-old allegedly threatened to stab them and then produced the folding knife. During questioning, the suspect did not admit the allegations. He remains in police custody.
