Polish police have detained 10 people and carried out security checks at more than 10,000 educational facilities as fears of further violence spread following two school knife attacks this week, one of which left a woman dead. The nationwide operation on Friday, 9 October, has included the detention of teenagers accused of making violent threats online or bringing weapons onto school premises. Authorities have urged parents and pupils to remain vigilant but say there is no evidence of a coordinated nationwide attack, despite rumours circulating on social media.
Poland’s national police headquarters announced the figures on Friday morning as officers intensified patrols around schools and investigated reports of potential violence across the country.
Police said they were examining threats, suspicious online messages and other incidents that could endanger pupils and school staff. The 10 detentions represented the national total reported that morning, rather than 10 confirmed planned attacks.

According to Reuters’ reporting on the police operation, the response followed widespread online rumours alleging that further school attacks were planned for Friday.
Officers from Poland’s Central Bureau for Combating Cybercrime (CBZC) have also been monitoring online activity and examining material potentially connected to the threats.
Teenagers detained over threats and weapons
Several of Friday’s police interventions involved minors suspected of making threats against schools or possessing potentially dangerous objects.
In Warsaw’s Mokotów district, officers detained a 14-year-old pupil found carrying a knife with a concealed blade and 11 firecrackers.
The Warsaw police account of the incident, reported by Radio dla Ciebie, said officers had responded immediately after receiving information about a possible threat. The case is to be referred to a family court.
Police also intervened in Pruszków County, near Warsaw, after two 15-year-olds reportedly published a video containing threats of violence.
Other interventions included reports of a 13-year-old in Warsaw who posted a photograph of a knife in a class group chat alongside threats directed at classmates.
Authorities are treating such reports seriously, although the circumstances and legal consequences differ between cases. A detention does not establish that an individual intended to carry out an attack.
Teenager charged over AI-generated school-threat video
In a separate development, police in the Mazovian town of Przasnysz confirmed that a 17-year-old had been charged after allegedly producing and circulating an AI-generated video suggesting that a dangerous incident could occur at a local school.
The video had spread online, contributing to concerns about possible further attacks.
According to the Mazovian police’s updated statement, investigators identified the teenager as the creator of the recording.
Police said he initially shared the video within a small, closed social-media group before it reached publicly accessible platforms.
Officers seized electronic devices and questioned other people as part of their investigation.
In an update issued at 1pm Polish time on Friday, police confirmed that the 17-year-old had been charged with causing a false alarm and making criminal threats.
He was placed under police supervision. The authorities said the offences could carry a maximum sentence of eight years’ imprisonment.
The charges concern the alleged creation and circulation of threatening material. They do not establish that a coordinated school attack was being organised.
Two serious school attacks in consecutive days
The nationwide security response follows two violent incidents in Poland’s Mazovia region on Wednesday and Thursday.
On 7 October, a 19-year-old attacked people at a vocational school in Ostrołęka, north-east of Warsaw.
Nine other people were injured, while the alleged attacker also sustained injuries. Investigators discovered a suspected improvised explosive device among his belongings.
A day later, 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 woman died from her injuries, while two other people were injured.
The Ostrołęka District Prosecutor’s Office confirmed that the suspect had been detained and that the case would proceed through the family and juvenile court system because of his age.
The attacks, occurring within approximately 24 hours of one another, prompted concern among parents, teachers and the wider public.
However, the proximity of the incidents does not establish that they were coordinated. Investigators have not publicly confirmed a common organiser or shared plan behind them.
Police reject rumours of a coordinated attack
Public anxiety intensified after social-media posts began claiming that further attacks would take place on Friday, 9 October, under the name of an alleged online challenge.
Police and government officials have warned that unverified claims could contribute to fear and potentially encourage further threatening behaviour.
Speaking to TVN24, Deputy Prime Minister and Digital Affairs Minister Krzysztof Gawkowski said authorities had found no evidence of a nationwide coordinated campaign.
He acknowledged that isolated individuals might communicate or attempt to imitate earlier incidents, but stressed that investigators had not established the existence of an organised national threat.
The distinction is important: authorities are investigating genuine threats and individual incidents, but have not verified the claims of a centrally organised wave of attacks.
Police have also urged social-media users not to circulate alarming videos or messages without checking their authenticity.
Schools increase security as parents keep children home
The incidents have disrupted education in parts of Poland.
Primary schools in the Wyszków municipality were closed on Friday following Thursday’s fatal attack, while some other schools adopted additional safety measures.
Authorities in several regions have increased the visibility of officers near educational facilities.
In a statement issued on Friday, police in Lublin province said officers had inspected approximately 1,000 educational facilities in the region on Thursday alone.
Patrols continued on Friday morning, with officers focusing on school entrances, surrounding streets and reports of suspicious behaviour.
Police in Małopolska also confirmed increased preventive patrols, including around primary schools, secondary schools and kindergartens.
Officers are coordinating with headteachers and local authorities, with checks inside educational institutions possible where circumstances justify them.
The intensified operation follows instructions from Prime Minister Donald Tusk for a stronger police presence around schools in response to the recent violence.
Authorities urge vigilance without spreading panic
The events have prompted a broader debate in Poland about school security, violent online content and the responsibilities of educational institutions and public authorities.
Police have emphasised that threats made online, even when subsequently described by their authors as jokes, can have serious consequences.
They have also stressed the importance of reporting credible concerns rather than sharing unverified warnings across social media.
Parents, pupils and school staff have been encouraged to pass information about potential dangers directly to schools or law enforcement. Immediate threats should be reported through Poland’s emergency number, 112.
As investigations continue, the authorities face the challenge of responding to genuine warning signs while preventing misinformation from escalating public anxiety.
The police operation remains active, and the number of detentions may change as further reports are investigated.
