Police received an alert that the women had fallen out of a window at around 6pm. She was taken to the hospital with serious injuries, but was unable to be resuscitated.

Police technicians have examined the apartment but have not found anything to indicate there had been an altercation.

“The technical investigation didn’t tell us too much about what happened,” Bo Paulsson of the Malmö police told TT.

Although there were no witnesses to the incident itself, the case is being treated as a homicide or manslaughter. During the night, a 32-year-old man was reported to be heard arguing with the woman inside the apartment. He was released after questioning, but has not been ruled out as a suspect, according to Paulsson.

Aftonbladet newspaper reports that the woman and the 32-year-old man, who has lived in the apartment for several years according to neighbours, were newlyweds and that she had only been in Sweden for a few days.
