A 15-year-old former pupil wearing a helmet-mounted camera killed one employee and injured two others at a Polish primary school yesterday, the second school stabbing in two days possibly linked to an internet challenge, authorities said.
A 37-year-old woman who worked as a caretaker had died in the latest attack, which took place at around 9am in Leszczydol-Nowiny, northeast of Warsaw, officials said.
On Wednesday, a 19-year-old wounded 10 people, including himself, at another school in Ostroleka, northeastern Poland, and police detained a 17-year-old in Sierpc in north-central Poland on suspicion of planning an attack.
“We fear a grim copycat phenomenon,” Prime Minister Donald Tusk told an emergency meeting.
“We are facing an extraordinary situation... for the first time, we are dealing with a killer who wore a helmet-mounted camera, intending to film the knife attack.”
It was not clear whether the attack was actually filmed.
He ordered police to visit schools daily in an effort to prevent further violence.
A police spokesperson said authorities had information that the incidents could be related to an internet challenge and that this was being investigated.
Nikola, the 18-year-old sister of a boy at the school, said that rumours about a challenge were circulating online.
