A Norwegian student found dead in London was last seen alive leaving an upscale nightclub frequented by movie and pop stars, UK police say.
Norwegian media say Martine Vik Magnussen went to the same school as the Norwegian royal family.
Martine Vik Magnussen, a 23-year-old business student, was found dead, hidden under rubble, in the basement of an apartment block in central London Sunday, the capital's Metropolitan police have said.
An autopsy carried out at Westminster Coroner's Court Tuesday revealed that she died from neck injuries, police said, and that "her death is thought unnatural, with suspected third party involvement."
Officers say that Magnussen was last seen alive sometime between 0200 and 0300 GMT on Friday March 14 at the Maddox nightclub in London's wealthy Mayfair district, more than a mile from where her body was found.
The Maddox says on its Web site that, since opening in April 2007, it "has been London's hottest member's club, attracting everyone from P Diddy to Kiera Knightly."
Police have appealed for a man of Arabic appearance, who Magnussen is believed to have left the club with, to come forward.
Several reports in the UK media have said that Magnussen was a family friend of John Fredrikson, one of Norway's richest men. Norwegian news Web site Aftenposten has reported that she was schooled at Oslo's well-known Kristelig Gymnasium, attended by members of the Norwegian royal family.
Metropolitan Police detective constable inspector Jessica Wadsworth, who is leading the investigation, said: "This is a tragic waste of a young woman's life. She had come to London to study and had her whole future in front of her. She was a very popular young woman with lots of friends and had a vibrant personality."
Magnussen was a student at Regents Business School at the time of her death. In a statement on the college Web site, Aldwyn Cooper, the college's CEO said: "On behalf of the College I want to express our condolences to everybody who knew Martine. Her family have already arrived in the United Kingdom and we will be in contact with them shortly.
"The College is deeply saddened by this news and our thoughts are with Martine's family and friends at this time. E-mail to a friend
