And according to prosecutor Klas Hellgren, the investigation is now closed.

- During a review, I have come to the conclusion that there is not enough evidence to proceed.

He continues:

- During the interrogation, no new evidence has emerged, but that does not mean that it can not appear more in the future.

But right now the investigation has been closed and Klas Hellgren can not say anything further about the case.

- There is pre-investigation secrecy.

It was the night between 15 and 16 June that the man was found.

He had wounds to the face caused by a sharp object and he was taken to hospital by ambulance.
