“The woman has been subjected to serious violence,” said Lars Johansson at Skövde police to news agency TT.
The woman was found by a relative. Her three-year-old daughter was in the apartment when police arrived at the apartment.
The 25-year-old man held on suspicion of murder is already known to the police. He is a resident of a town in Västra Götaland county in western Sweden.
“We know that there is a link between the man and the dead woman. They have been in contact over the internet. We are working on a theory that explains the motive of the crime, but I do not want to go in to specifics,” Johansson said.
The police investigation continues on Saturday. The woman’s apartment was examined by police technicians on Saturday morning and the police confirmed plans to interview several more people during the course of the weekend.
The 22-year-old victim is not previously known to the police.
Her three-year-old daughter is now in the care of relatives.
