It was at 5.30 pm that the police went on an alarm to the full beach Näsetbadet. Several witnesses had called about an ongoing quarrel, or alternatively assault.

- It all ended with a report of aggravated assault. But we have neither a known perpetrator nor a plaintiff, says duty officer Sebastian Börjesson.

However, there are several witnesses who have been questioned on the spot.

- There has also been talk of a knife on the spot but we do not know for sure yet, says Sebastian Börjesson.
