A dispute during documentary filming in Vienna escalated into violence, police said, after a 16-year-old was hit in the face during a brawl. For the production shoot in the Perfektastraße, a company invited around 80 to 90 people. The argument allegedly began when one participant made remarks about another woman present, and about ten people became involved in the fight, police added. The 16-year-old and his 18-year-old brother, along with a friend, tried to calm the situation. During the confrontation, the 16-year-old was injured by a punch delivered by a 19-year-old. After the situation briefly de-escalated, the 19-year-old returned with a knife. He threatened the three young men, but officers were able to take the knife away. No one was injured with the blade. Police arrested the 19-year-old at the scene and then imposed a temporary weapons ban. Investigators also said the man is a Syrian citizen.
