Poland has launched a nationwide security operation after three knife attacks at educational institutions left one woman dead and more than a dozen people injured. Police have detained 117 people amid a wave of online threats, while intelligence officials are examining whether Russian disinformation networks exploited the violence to spread panic.

Poland is confronting an unprecedented school security crisis after a succession of violent attacks by young people triggered widespread fear, school closures and a nationwide police mobilisation. By Sunday, 11 October, officers had detained 117 people and conducted nearly 64,000 security checks at educational establishments, as the authorities attempted to contain both genuine threats and an escalating campaign of intimidation on social media.

The crisis reached its height on Friday, 9 October, when warnings circulated about a supposed nationwide killing campaign known as “Bloody Friday”. Videos, threatening messages and lists of potential targets spread through TikTok, messaging platforms and school discussion groups, prompting parents to keep children at home and several local authorities to suspend classroom teaching.

Although police have found no evidence of an organised nationwide conspiracy, the violence that preceded the rumours was real. Three separate attacks took place between 7 and 10 October, while investigators are examining hundreds of other incidents involving threats or suspected criminal activity.

Two attacks that triggered nationwide panic

The first major incident occurred on Wednesday, 7 October, at a vocational school in Ostrołęka, north-east of Warsaw. A 19-year-old student armed with a machete attacked pupils, teachers and other people in and around the building, injuring nine victims before harming himself.

Investigators subsequently discovered a homemade explosive device inside his backpack. The suspect was arrested, and prosecutors brought nine charges against him, including attempted murder. The discovery of explosives raised further questions about the extent of his preparations and the possibility of a substantially higher death toll.

The following day, a 15-year-old former pupil entered a primary school in Leszczydół-Nowiny, near Wyszków, and attacked three members of staff with a knife. A 37-year-old caretaker died from her injuries, while two teachers, including the headteacher, were wounded.

According to investigators, the teenager wore a helmet-mounted camera, raising suspicions that he intended to record the assault. The official prosecution statement confirmed the victim’s death and the detention of the suspect.

The attacks were followed by threatening messages from other teenagers, including a video attributed to a 17-year-old in the Przasnysz district who claimed to be participating in a competition involving killings. Police subsequently detained him. In Sierpc, another 17-year-old was arrested after allegedly discussing plans for violence at school; officers discovered two knives.

Thousands of schools under police surveillance

The rumours produced an immediate reaction. Schools in Wyszków, Ciechanów, Pułtusk and other municipalities cancelled classroom teaching or introduced remote lessons. Elsewhere, parents independently withdrew their children, leaving some classrooms largely empty.

Police launched an extensive preventive operation, deploying additional officers around schools and investigating online threats.

According to the figures released on 11 October, the authorities had recorded 275 incidents requiring investigation, detained 117 people and carried out nearly 64,000 checks at schools, nurseries and other educational facilities.

The situation deteriorated further on Saturday, 10 October, when a 21-year-old student attacked three people at a post-secondary educational institution in Warsaw. Two 17-year-old girls and a 24-year-old woman were injured. One victim required hospital treatment, although none of the injuries was considered life-threatening.

Interior Minister Marcin Kierwiński subsequently stated that investigators had established no links between the recent attacks. The authorities nevertheless remain concerned about imitation offences, particularly where threatening material circulates among teenagers through closed online communities.

Russia’s possible role in spreading panic

The events have also raised questions about whether hostile foreign actors deliberately amplified the crisis. Tomasz Siemoniak, Poland’s minister responsible for coordinating the intelligence services, warned that Russian organisations routinely exploit domestic emergencies to spread disinformation and undermine confidence in public institutions.

In his statement on 9 October, Siemoniak acknowledged the possibility of foreign involvement but stressed the need for evidence before assigning responsibility.

There is, at present, no publicly established evidence that Moscow organised the school attacks or directed the subsequent threats. Nevertheless, the rapid circulation of alarming videos, fabricated warnings and unverified target lists illustrates how genuine violent incidents can be exploited to disrupt everyday life without further physical attacks.

The episode also presents a challenge for European regulators. Poland is examining measures against dangerous online content, while its existing obligations under the EU Digital Services Act provide a framework for addressing systemic risks associated with major platforms.

For Donald Tusk’s government, the immediate priority is preventing further attacks as schools reopen under heightened security. The longer-term challenge concerns the interaction between online radicalisation, copycat violence and disinformation capable of transforming isolated crimes into a national emergency.
