Police were called at 11:30 a.m. Sunday to a suspected murder in an apartment building.
Residents of the house reacted to hearing screams, says police spokesman Daniel Wikdahl.
A seriously injured 55-year-old man was found in an apartment. Despite emergency medical care, he could not be saved.
The suspect was in another part of the house when detained. He was arrested later that day, Expressen writes.
Daniel Wikdahl cannot say whether the man and the victim know each other.
The police have also brought in one person for questioning. That person is not suspected of any crime.
We believe this person has important information about what happened, says Daniel Wikdahl.
The crime scene has been cordoned off for a technical examination.
