A woman in her 30s has been charged with murder after a man in his 20s died after being injured in an apartment on Grünerløkka in Oslo.

The dramatic violent incident is said to have taken place in an apartment in Grünerløkka, north-east of central Oslo.

The police were notified of the incident at 5.30pm on Sunday.

The first information was that the man was found bleeding and received medical treatment on the spot. It did not appear to be a fatal incident.

A woman in her 30s was also in the apartment when the emergency services arrived at the address on Grünerløkka.

But the man’s situation turned out to be more serious than expected. Life-saving first aid was administered, but after half an hour he was pronounced dead as a result of the injuries he had sustained.

NTB reports on the case.

The man in his mid-20s has unfortunately been confirmed dead. The woman in her 30s who was at the scene has been arrested. We are working to get in touch with any witnesses and discuss the injuries of the victim, says operations manager Guro Sandnes in the Oslo police district.

The woman has been charged with murder, crime leader Kjersti Myhre tells VG.

The police came to the apartment and found a man who was seriously injured and a woman whom we believe is connected to the incident. She was arrested on the spot, says police task leader Svend Bjelland to NTB.

The police state that the woman was unharmed and that the arrest took place without drama. But they will not say anything about whether weapons have been seized at the scene.

Bjelland says to NRK that there is some form of relationship between the two.

Grünerløkka in particular has been one of the most frequently discussed crime scenes in connection with serious violent crime in recent times. Document has written about several such cases in recent months.
