The police received an alarm about the assault at 18.22.

On the spot, they were able to arrest a man in his 20s, then suspected of attempted murder.

Some form of stabbing weapon must have been used in the assault.

- We do not want to go out with the type of stabbing weapon in question, but we are working full time on the spot to gather evidence, interrogate witnesses and secure the place for a technical investigation, said Hans-Jörgen Ostler, press spokesperson at the police in region West at 7 p.m.

What caused the fight is unclear.

At 10 pm, the police wrote on their website that the man had died and that relatives had been notified, which several media were quick to report.

The update was then removed, as it was said to be about another event during the evening.

At 23.15, however, regional guard officer Martin Hallberg confirms that the injured man has died.

The arrested man is suspected of attempted murder.
