"Dad is taken and upset," says Ola Österling, press spokesman at the police.

There is no injury situation on the boy, but the children who should have threatened him with knife should also have shouted something to the boy.

- Yes, it should also have been a verbal attack, but we do not know what was said.

The children left the scene after the father intervened and the police searched for the children with both dog patrol and helicopter.

During Monday night, there was no suspicious motive for the incident, which has been classified as illegal threat.
