Polish Police Arrest 10 Over School Attack Threats Amid 'Bloody Friday' Rumors

Polish police detained 10 people on Friday, most of them young, over threats tied to school attacks, according to authorities. Among those held was a 13-year-old who shared a picture of a knife in a class group chat and threatened fellow students. The arrests followed two stabbing sprees within two days, which triggered online rumors of a "Bloody Friday." In response, a nationwide security operation was launched, with officers sent to 10,000 schools. The government cautioned against spreading false information that officials worry might encourage copycat attacks. Digital Affairs Minister Krzysztof Gawkowski said much emotionally charged misinformation was circulating online, describing it as spontaneous reactions rooted in understandable anxiety, while stressing there was no indication of any nationwide "challenge" underway.
