Plans for arson are being investigated after a note at a school in Arvidsjaur

It was during Tuesday that a note, which could be interpreted in different ways, was found at Sandbackaskolan's gymnasium. After contacting the police, the school released information via a school platform on Wednesday morning.

"The police have initiated an investigation due to this finding and announce that there is no threat. According to the police, there is therefore no reason not to continue teaching as normal," wrote school director Peter Andersson.

Preparation for arson

Aron Backman, head of investigations for the police in Pite älvdal, confirms that they have drawn up a report of preparation for arson. But there are no suspects at this time.

- This is how we work to see if we can strengthen that suspicion or dismiss the case. The work on the investigation continues during the day, he tells SVT.

The police do not want to comment on what was written on the note that was found. On the other hand, they deny information that has been circulating in some forums that the note should have been about a threat of a school shooting.

- That has never been the case and is something taken out of context, says Backman.

Some concerned parents tell SVT that their children have stayed at home on Wednesday.

SVT is looking for a school principal.
