WARSAW: A 19-year-old on Wednesday stabbed nine people with a knife at his vocational school in Poland, north of the capital Warsaw, wounding stude­n­­ts, teachers and passers-by.

The teen was arrested after the rampage at a school in Ostroleka, 120 kilometres from Warsaw, said police, who released a blurred photo following his arrest. Mariusz Frank­owski, the top local official, said five students, two teachers and two passers-by were injured.

“The lives of none of the injured are in danger,” Mariusz Zeranski, Ostroleka police spokesman, told reporters.

Elzbieta Lukasiewicz from the Ostroleka prosecutor’s office said: “The boy entered the school and attacked the students and teachers with a dangerous tool.” The teen was arres­ted by the police about 20 minutes after the attack, not far away from the school. He was treated by emergency services after having “self-harmed,” the prosecutor’s office said. He is now out of hospital and in police custody.

Bomb disposal experts took away a bag the assailant had left at the high sch­­ool. The school was clo­sed as a precautionary measure.

The attack comes just a few days after a priest was stabbed by a Ukrainian in a monastery in a Polish region near Ukraine. Social networks on Wednesday were again full of rumours that the attacker was Ukrainian.
