A 15-year-old former student attacked three people with a sharp instrument at a primary school near Wyszkow, northeast of Warsaw, on Thursday morning, leaving a 37-year-old female school employee dead.
Tragedy Unfolds at the Wyszkow Primary School
The victim, identified by the Onet.pl portal as a 37-year-old female school custodian, could not be saved despite resuscitation efforts, the Mazovian police announced on the social platform X.
The incident unfolded around nine o’clock in the morning inside the local primary school building, where the teenage attacker came onto the school grounds during class hours and struck on a corridor. Two other staff members sustained injuries during the confrontation. A female teacher was wounded, and the school director suffered injuries while actively subduing the teenage assailant before police arrived to take him into custody. Because the suspect is a juvenile, the case will be handled by the court department responsible for juvenile delinquency, and motives for the attack remain unknown as investigators begin their work.

A Rapidly Escalating Wave of School Security Incidents
Thursday’s violence follows closely on the heels of a major incident a day prior. Mazovian Voivode Mariusz Frankowski confirmed that ten people total, including the perpetrator, five students, two teachers, and two individuals nearby, were hurt in the Ostrołęka assault, where a 19-year-old vocational school student used a machete to attack nine people and then harmed himself. To put an end to the speculation beginning to appear in the media: he is a Polish citizen,
Frankowski stated, noting that the suspect lives in Ostrołęka and attends the targeted school. The 19-year-old carried out the attack during class hours in the fourth-grade section, afterwards fleeing the scene before police apprehended him at a municipal beach by the Narew River, where he also required medical treatment after attempting to take his life. Prosecutors are treating the case as attempted murder. Pyrotechnics later discovered a homemade explosive device inside the 19-year-old’s discarded backpack, which nearly detonated before alert students and a teacher threw it out of a classroom window.
Authorities detained a 17-year-old youth who had announced intentions to commit violence at a local school. Officers seized two knives and found internet searches regarding the Ostrołęka attack on his mobile phone.

Prime Minister Tusk Convenes Security Meeting After Violent Episodes
In response to the cluster of violent episodes, Polish Prime Minister Donald Tusk convened a security meeting on Thursday. The gathering included the interior minister, the heads of the education and health ministries, and the chief commander of police.
An unnamed government security official speaking to Onet.pl indicated that authorities are actively investigating whether outside radicalization played a role in the attacks. But it must be kept in mind that one attack that receives a lot of attention brings followers into activity,
the official cautioned.

Reacting immediately to the crisis, Andrzej Fijolek, spokesperson for the police headquarters, announced that law enforcement agencies would step up preventive checks around educational facilities nationwide. Police patrols are placing a specific focus on individuals in the immediate vicinity whose behavior suggests potential danger to students and staff.
