It was relatives of the girl who alerted the police after the girl did not come home on Sunday evening. Before the police came to Norrsundet, however, relatives had found the girl and she was very shocked at what had happened.

- We can't say that much more right now. But she was assaulted and we label it as a gross rape attempt, says Mikael Hedström, press spokesman at the police.

Tips from the public

Technicians have worked all night at the suspected crime scene to secure any traces. The police are now working to knock a door in the area to find testimony.

The police also want tips and observations from the public.

- We are really looking for all the observations that you think have been a different behavior. It may be one person, several persons or vehicles that have moved in the area in a different way. If there is something that you have reacted to, then you should contact us and tell it, says Hedström.
