According to the spokesman, preliminary information suggested that around four to five students were injured. The police therefore assumed that the perpetrator had a “connection to the school”. In this context, the spokesman referred to a recent message from the school management to parents, according to which the alleged attacker was a 17-year-old high school student with an acute mental illness.

According to the police, the crime was committed with a stabbing weapon; further details about this and other details were not initially available. A major operation was underway at the affected high school. “The building has been evacuated – the students are safe and are being looked after,” said the emergency services.

According to media reports, special police forces were deployed at the school. After the attack, the emergency services found the suspect bleeding inside the school building and arrested him.
