AKIPRESS.COM - The Danish inventor Peter Madsen has admitted dismembering the body of Swedish journalist Kim Wall aboard his submarine, but denies killing her.

Danish police said in a statement that he also admitted dumping her body parts in the sea, BBC reported.

He told police she had died in August from carbon monoxide poisoning inside the submarine, while he was up on deck.

Mr Madsen had previously denied cutting up her body and said she died when a heavy submarine hatch fell on her head.

Divers found bags containing her head, legs and clothing in Koge Bay, just south of Copenhagen, earlier this month. Police said they had been weighed down with pieces of metal.

Ms Wall's torso was found on 21 August. A post-mortem examination revealed knife wounds to her genitals and ribcage, which were believed to have been caused "around or shortly after her death".

Police said on Monday they were extending the charges against Mr Madsen - which already include murder and mutilating Ms Wall's body - to include sexual assault without intercourse. The inventor denies the charges against him.
