The police received the alarm just before 9pm on Monday evening.

A caller found the man injured in the stairwell.

He was then taken to hospital, but it is unclear how seriously injured the man is.

- What type of stab and cut injuries it is far too early to say.

It is too early to interrogate the injured man, says Rickard Lundqvist.

Forensic technicians have been sent to the scene to carry out a technical examination.
