On Saturday, October 10, a 21-year-old student attacked three women — two 17-year-old girls and a 24-year-old woman — at an adult school on Minsk Street in Warsaw. This was reported by the Polish news channel TVP.Info. One of the victims, a 17-year-old girl, sustained a stab wound and was taken to the hospital. According to medical staff, her life is not in danger. The other two victims received medical assistance at the scene. According to law enforcement, police arrived at the educational institution just four minutes after receiving the call. By that time, one of the school staff had already managed to neutralize the attacker. The suspect was detained. Preliminary reports indicate that the girl was not acquainted with the victims, who had come to the institution to submit documents for enrollment. The reasons for the attack remain unknown. **Three Attacks in a Few Days** The incident in Warsaw was the third such case in Poland in less than a week. On Wednesday, October 7, a 19-year-old man carried out an attack at a school in the city of Ostrołęka. As a result, nine people were injured. The next day, on October 8, another attack occurred at an elementary school in the village of Leszidole-Nowiny in the Masovian Voivodeship. According to police, a 15-year-old teenager attacked three people. One of the victims, a 37-year-old staff member of the institution, died from his injuries. **Police Checked Nearly 50,000 Schools** After a series of attacks, Polish law enforcement has increased security measures in educational institutions. On Saturday, October 10, police reported the detention of 76 individuals across the country and conducted checks in nearly 50,000 schools. According to the Associated Press, these measures are aimed at preventing new incidents of violence. At the same time, law enforcement emphasizes that they currently have no evidence indicating coordination among the three attacks. Investigators will need to establish the motives for each of the crimes and determine whether there are any connections between them, writes "Deutsche Welle."
