Half an hour after the incoming alarm, the police arrested a man in his 30s. He is currently suspected of attempted murder and a report has been prepared.
"The crime scene has not been ascertained yet, the police are working on it," says Nils Norling, press spokesman for the police region South.
The woman is still being cared for in hospital but the injury is not life threatening. It is still unclear who contacted the police in connection with the incident.
The man and the woman have known each other since before, but the relationship between the people is still unknown.
