 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. 
  
 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. 
  
 Ms Wall, 30, was last seen alive on the evening of 10 August as she departed with Mr Madsen on his self-built 40-tonne submarine, UC3 Nautilus, for a story she was writing about his venture. 
  
 Her boyfriend raised the alarm the next day when she did not return from the trip. 
  
 Initially, Mr Madsen said he had dropped her off safely in Copenhagen, but the 46-year-old later changed his story to say there had been a "terrible accident", that he had "buried her at sea" and planned afterwards to take his own life by sinking his submarine.

 Danish Prosecutor Jakob Buch-Jepsen told a court earlier this month that footage of women being decapitated alive had been found on a hard drive believed to belong to Mr Madsen. Mr Madsen said the hard drive was not his. 
  
 The inventor was supposed to appear in court on Tuesday but will now remain in custody until 15 November. ||||| FILE - This April 30, 2008 file photo, shows a submarine and its owner Peter Madsen.

 TALLINN, Estonia (AP) — A Danish inventor has admitted dismembering a Swedish journalist who disappeared from his home-made submarine in August and has changed his story about how she died, but still denies killing her, police investigating the bizarre case said Monday. 
  
 According to Copenhagen police, Peter Madsen now says Kim Wall died as result of carbon monoxide poisoning inside the submarine while he was on deck. Previously he had said she died after being accidentally hit by a heavy hatch in the submarine's tower. 
  
 "This explanation (by Madsen) naturally will lead the police into gathering additional statements from the coroner and the armed forces' submarine experts," said Copenhagen police investigator Jens Moller Jensen. 
  
 Police say Madsen acknowledged he dismembered her body and threw it into Koge Bay southwest of Copenhagen.. 
  
 Wall's torso was found on a southern Copenhagen coast in late August, and her head, legs and clothes were found at sea this month. No fractures to Wall's skull were found that would have supported the claim that she was killed by the hatch. 
  
 Wall was working on a story about Madsen and was last seen aboard his home-made submarine Nautilus as it left Copenhagen in August. 
  
 The next day, Madsen was rescued from the sinking submarine without Wall. Police believe he deliberately sank the vessel. 
  
 Madsen's pre-trial detention is set to expire Tuesday but police said no new hearing will be held as the 46-year-old has voluntarily agreed to remain in detention. |||||

Peter Madsen's recounting of journalist Kim Wall's August death has changed yet again, from that he last saw her alive, to that it was an accident involving a hatch cover, to the latest: that she succumbed to carbon monoxide poisoning within his submarine while he was on deck. And while he still says he didn't kill her, he now admits to mutilating her body post-mortem by dismembering it and throwing it into the sea. Wall's head was found in a sunken bag in Koge Bay in early October, and the find was problematic for Madsen in that the head showed no damage that would back up Madsen's previous story that the sub's heavy metal hatch struck Wall, killing her. "This explanation [by Madsen] naturally will lead the police into gathering additional statements from the coroner and the armed forces' submarine experts," said Copenhagen police investigator Jens Moller Jensen, per the AP. The BBC reports a new charge of sexual assault without intercourse has been issued.
