Police in Denmark say a Danish inventor has admitted dismembering a Swedish journalist who disappeared from his submarine, but says he did not kill her.

Police are still uncertain on the cause of journalist Kim Wall’s death, despite the ongoing investigation revealing that she was stabbed several times.

Danish police on Wednesday identified a headless female torso found in the Copenhagen waterside as that of Swedish journalist Kim Wall, who police believe was killed on a home-made submarine, The Independent reports. 

"DNA match between torso and Kim Wall," the police said on Twitter, declining to comment further until a press briefing later at wednesday.

A cyclist in the Amager district of Copenhagen discovered a defiled woman's body, her head, hands and legs were missing. Police link the case to the investigation of the mysteriously missing Swedish journalist Kim Wall, for which a search operation has been running since last Friday.

Danish police said on Sunday they had found nobody in the wreck of a submarine owned by an inventor charged with the manslaughter of a woman who had been on board – but added the vessel seemed to have been deliberately sunk.
