A boy has been arrested after he published video threats on YouTube's Website which were similar to those seen before a school massacre occurred in Finland.

Norwegian police say that the videos contained threats to Erdal Junior High School in western Norway. The videos had direct links to reports of a school massacre in Finland earlier this month, including a picture of that school.

Yesterday, 280 pupils were searched and had to go through metal detectors before entering the school building, and one person was arrested.
