Norwegian woman had neck injuries

Ms Vik Magnussen moved to London last year to study business

A Norwegian woman found murdered had sustained significant injuries to her neck, post-mortem tests have revealed.

Martine Vik Magnussen's body was found partially hidden under rubble in a basement in Great Portland Street, central London, on Sunday morning.

The 23-year-old was last seen leaving the members-only bar, Maddox club, in nearby Mayfair on Friday morning.

Police said they are looking for a man with whom Ms Vik Magnussen is thought to have left the club.

Police said "her death is thought unnatural with suspected third party involvement".

Further examinations are being conducted on her body to find out the exact cause of death, police said.

'Tragic waste'

Forensic science experts have been searching the block of privately owned flats where the body was found.

Det Ch Insp Jessica Wadsworth 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."

Ms Vik Magnussen moved to London in February last year and began studying business at the Regent's Business School, Regent's Park.

Its head, Professor Aldwyn Cooper, said: "The college is deeply saddened by this news and our thoughts are with Martine's family and friends at this time."

No arrests have been made and the investigation was at an "early stage", a Metropolitan Police spokesman said.

Ms Vik Magnussen's parents, brother and sister have flown to the UK from Norway.
