Series of knife attacks at schools in Poland

Poland was previously considered a relatively safe country compared to Western Europe and America, but recently knife attacks in schools have shocked the country. Three women were injured in another attack today. It happened in Warsaw at a school for teenagers and adults. Classes took place there today.

A 21-year-old student stabbed three young women in the school office who were about to hand in documents. A school employee took the knife away from the attacker and then handed it over to the officers who were called, said a police spokesman.

A 17-year-old student was taken to hospital with cuts to her forearms. The other two victims, aged 17 and 24, were treated on site. The motive for the crime is still unclear. The suspect and the victim did not know each other.

Police see no connection with other attacks

It is the third knife attack in a Polish school in just a few days. On Thursday, the caretaker was killed and two other people were injured in a knife attack by a 15-year-old at a school in Leszczydol-Nowiny, about 70 kilometers northeast of Warsaw.

Prime Minister Donald Tusk said the attacker was wearing a helmet with a camera attached to it. "It was his intention to film the knife attack."

On Wednesday, a 19-year-old injured nine people with a knife at a vocational school in Ostroleka, almost 100 kilometers north of Warsaw, two of them seriously. The police spokesman said there was no evidence so far that the latest attack was related to the other crimes.

Almost 60 schools closed on Friday

Investigators are currently investigating threatening messages on the Internet such as announcements, photos and videos, most of which were published by teenagers. The police speak of 231 suspected cases. 76 people were arrested.

The situation at schools is tense. According to the Ministry of Education, almost 60 schools in Poland were closed on Friday. Many tightened entry controls.
