Police arrested a 16-year-old girl in Zielonki after she published a dangerous video online and tagged where a similar threat could occur. Zielonki officers from the local police station stopped her on 14 October, days after the footage appeared on a social media platform. The filmed incident showed an unsafe situation, and the post included a caption indicating a location where the danger could arise again. Police said the content matched a pattern of recent incidents and disruptions in schools. The case remains at the investigation stage following the arrest.
