Three people were injured in a stabbing at a college in Warsaw on Saturday. Police spokesman Jakub Filipiak told Reuters that police received a report of a dangerous-weapon incident at 12:30 p.m.
One of the injured was taken to hospital with non-life-threatening injuries, while the other two did not require hospital treatment. Filipiak said the alleged attacker was a 21-year-old student at the college.
Polish state news agency PAP reported that the victims were two 17-year-old girls and a 24-year-old woman who had come to the college to submit registration documents. According to the agency, an initial police investigation indicated that the attacker and the victims did not know one another.
Police increase security measures at schools
The incident followed two separate knife attacks at schools during the week. On Friday, October 9, thousands of police officers visited schools across Poland to ease concerns about possible further violence after the attacks. Saturday’s stabbing is expected to heighten those concerns.
Police said that since Friday, they had inspected about 50,000 sites and detained 76 people. Authorities previously said most of those detained were teenagers who had posted threats online.
Two more school attacks reported during the week
On Thursday, a 15-year-old former student, wearing a helmet fitted with a camera, killed a school caretaker and injured two teachers at a primary school in Leszczydol-Nowiny, northeast of Warsaw.
A day earlier, a 19-year-old injured 10 people, including himself, at a school in Ostroleka, north of the capital.
The latest incidents have heightened concerns about violence among young people and the possibility of further attacks.
