Norwegian police recently shut down a high school near Oslo when a video warning of massacre at the Kjenn school was revealed on the YouTube video-sharing website.
The 15-year-old student who posted the video clip has not been arrested, although he has admitted posting the video. His name has been revealed.
Police chief Jens Bruun said the police would speak to the boy and his father about the incident but did not believe the student possessed any weapons.
The 50-second video showed a photo of the school and six teachers working there, as a voice said: “It will happen one day, it will be a bloody machine, one day you will die.” The video was posted on YouTube on Saturday and removed the following day.
Nordic schools have seen several closures and evacuations since Finnish student Pekka-Eric Auvinen killed eight people and himself at Jokela High School on 7 November. Auvinen had previously posted videos on YouTube outlining his plans for massacre.
