Twice during November and December, Västervångskolan in Landskrona had to be evacuated.
The 800 students had to go home after the school was somehow threatened via a website.
The police did not assess the threat as serious either time, but the city of Landskrona still brought in guards for a period just to be safe.
Since then, it has been quiet at the school.
But now an investigation is underway into the two threats.
Young person may be involved
- Someone is singled out and investigated under the Young Offenders Act, a person who is under 15 years of age.
But we'll see where the investigation leads, says Sofia Björk, assistant prosecutor and preliminary investigation leader, to SVT Nyheter Helsingborg.
Because it concerns such a young person, she does not want to comment further on the investigation.
"Good about the threats for explanation"
Erik Åström, director of operations for the school in Landskrona, thinks it is good if the threats are explained.
- It would of course be nice for everyone involved, And that person in that case gets support and help, he says.
