- It is not possible to prove that he intended to threaten anyone. He has said it was fun, says Jakob Semark, prosecutor and investigator.

What do you think he did as a joke?

- Yes, it might not be so appropriate.

Back to school

It was last Friday that the boy appeared masked and was threatened at Teknikum in Växjö. The incident caused a massive police call. The 15-year-old was picked up for questioning during the evening but was then free to go.

- He has never really been detained.

On Thursday, Jakob Semark made the decision to close the preliminary investigation into illegal threats and violations of the knife law.

- I made that decision after reading all the interrogations.

The 15-year-old boy has been back in school since Wednesday.
