Poland detains 76 and heightens school security after attacks

By the Editorial Team · Sunday, October 11, 2026

Polish police arrested 76 individuals and conducted inspections at nearly 50,000 schools following two knife attacks by minors in the Mazovian province that resulted in one death and multiple injuries. These rare violent incidents have prompted nationwide security enhancements, including temporary school closures and increased patrols, as authorities work to prevent further attacks and address safety concerns.

Polish authorities intensified security measures and detained dozens of individuals following two violent attacks at schools earlier this week, prompting nationwide concern over rising school violence. On Saturday, police announced the arrest of 76 people across Poland and reported that nearly 50,000 schools had been checked as part of preventive efforts to avoid further incidents.

The attacks, which occurred on Wednesday and Thursday in the Mazovian province near Warsaw, left one person dead and several others injured, including children. On Wednesday, a 19-year-old student at a vocational school attacked students, teachers, and passersby with a sharp weapon, injuring nine before fleeing and later being detained by police. The following day, a 15-year-old at his former school fatally wounded a custodian and injured two others in a knife attack. Both assailants are Polish nationals and remain in custody.

These incidents marked a troubling development in Poland, where violent attacks in schools by minors have been rare. In response, schools across the country boosted security on Friday; 59 institutions temporarily suspended classes, mostly in the Mazovian district. Many parents opted to keep their children home, and police increased patrols around educational facilities. School officials reported implementing measures such as additional staff at entrances and voluntary backpack searches to enhance safety.

Interior Minister Marcin Kierwiński emphasized the government’s firm stance on safety, stating, “There will be no compromise here. The safety of the youth is the most important thing.” Among those detained were minors found carrying weapons, including a 14-year-old boy discovered with a knife concealed on his person and firecrackers, and a 16-year-old who brought a butterfly knife to school. Authorities also apprehended individuals who had posted images of knives online or made threats against their peers or schools.

Despite widespread rumors circulating on social media and among parents about a coordinated series of attacks referred to as “bloody Friday,” officials have found no concrete evidence linking the two assaults or indicating an ongoing online challenge encouraging violence in schools.

The government has pledged to maintain heightened security measures and to organize crisis training for school personnel. Prime Minister Donald Tusk remarked on challenges faced by law enforcement in the digital age, noting that if the younger attacker had streamed his assault live online, current legal frameworks would have made it difficult to block the content promptly.

During Thursday’s attack, after injuring three adults, the 15-year-old, who wore a camera to document his actions, was subdued by school director Krzysztof Ochmański. Ochmański recounted that at one point, the attacker appeared to grasp the severity of his actions and sought help, even requesting a hug. The episode has left parents and authorities grappling with ways to address school safety and the underlying causes of such violence.
