Polish police have taken a series of teenagers into custody following a wave of online threats targeting schools. The arrests were made as authorities worked to stabilize public sentiment after rumors of a coordinated 'Bloody Friday' attack began circulating on social media. The panic was exacerbated by two separate stabbing incidents that occurred in the country over the span of two days, leading many to fear a larger, organized trend of violence.

Despite the widespread speculation on social media platforms regarding an 'online challenge' that might be inciting these threats, law enforcement officials have stated that their investigations have yielded no evidence to support the existence of such a challenge. Police are currently treating the threats as isolated incidents rather than part of a broader, organized movement. The government has responded to the heightened state of alarm by implementing nationwide security measures to ensure student safety as the situation remains under investigation.
