The alarm came in at 03.40 to the police who sent several patrols to an address in Enköping.

In the apartment, there was a woman in her 35s who suffered cuts to her forehead and hand, which UNT was the first to tell.

A man was also found, also with cuts.

However, no one should have received life-threatening injuries.

The woman was taken to hospital with minor injuries.

The police arrested the man and he is now suspected of attempted murder.

The police have cordoned off the apartment for technical investigation.

- A dramatic start to this day, states police spokesman Magnus Jansson Klarin.
