A Danish inventor and owner of a huge DIY submarine has been accused of manslaughter after the disappearance of a female journalist who had been on board before it sank, police said yesterday.
Peter Madsen was arrested Friday on preliminary manslaughter charges after his 40-ton, almost 18-meter-long (60-foot-long) submarine sank off Denmark's eastern coast.
Danish police would not comment on why charges had been brought before a body had been found, but said they would offer another update later on Saturday after Mr Madsen appears in court.
Today a Danish judge ruled Madsen would be detained for 24 days while police investigate what happened before the ship sank.
Ms Hald Engmark said Madsen is "willing to cooperate" and has not decided whether to appeal the detention ruling.
Madsen told police he had dropped off Wall not far from where their journey began, but after she was later reported missing, authorities suspected she may have been inside the submarine when it sank.
Kim Wall's family said in statement emailed to The Associated Press on Saturday, "It is with great dismay that we received the news that Kim went missing during an assignment in Denmark".
The missing woman has been identified as Kim Wall, a 30-year-old New York-based freelance journalist who has written for the New York Times, the Guardian and Vice Magazine.
Mr Madsen appeared calm during an interview with Danish television shortly after the submarine sank, saying: "I am fine, but sad because Nautilus went down".
Ms Wall had been writing about Mr Madsen and his submarine, which at one stage was the largest privately-made vessel of its kind.
She also received a master's degree in journalism from Columbia University in NY in 2013.
The submarine sank on Friday, but Madsen says Wall disembarked on Thursday night.
Local broadcaster TV2 aired footage of Madsen getting off the private boat and giving a thumbs-up sign, but the journalist was nowhere to be seen. The 40-ton, 18-meter-long craft named UC3 Nautilus was his third submarine project.
"It took about 30 seconds for Nautilus to sink, and I couldn't close any hatches or anything", Madsen said.
The woman's boyfriend alerted authorities that the sub had not returned, prompting a major maritime search. He claims he dropped the woman off at Refshaleøen three hours later.
