“Forensic experts were on the scene until late last night and they are continuing their work during the morning,” said Lotta Daniels of the police to local paper Norrbottenskuriren on Tuesday morning.
Police received a call and arrived at the flat around 7pm. There they found the woman dead.
A man, born in 1955, was later brought in by police for questioning. He is under suspicion of murder or alternatively manslaughter and had allegedly been found in the flat with the dead woman.
According to local police, the man is not previously known to them and they are not aware of any connection to the woman.
“It is not a person close to the woman who has been brought in. The woman lived in the flat, the man at another address,” said Erik Kummu of the county police to newspaper Norrländska Socialdemokraten.
According to Norrbottenskuriren, no weapon was found on the scene of the crime.
The investigation into the suspected murder will continue over the course of Tuesday.
