Detectives searching for missing oil executive Carole Waugh have found the body of a woman in a lock-up garage in London.
Miss Waugh, 50, originally from Durham, has not been seen by her family since mid-April and concerns for her safety grew after a fraudster tried to sell her central London flat by posing as her brother.
Scotland Yard said a woman's body was found in a garage in Lime Court, New Malden, south west London, last night.
Earlier this week a 47-year-old man was arrested on suspicion of kidnap and conspiracy to defraud and subsequently on suspicion of murder.
The suspect is in custody at a south London police station. A warrant for further detention was granted at Croydon Magistrates' Court yesterday, Scotland Yard said.
The body has not been formally identified and was taken to Kingston mortuary. A post-mortem examination will take place later today.
Ms Waugh, of Harrowby Street, central London, was reported missing by her family on May 7 and had never gone missing before.
The last believed sighting of her was thought to be in central London three days earlier, but this was unconfirmed.
To date, 10 people have been arrested in connection with the investigation.
Detectives said Ms Waugh, who previously lived in Libya, met men through a variety of internet sites including dating websites and were investigating the possibility that she might have been an escort.
Detective Chief Inspector John McFarlane said on Wednesday: "Information has been received which has progressed this inquiry and we are now treating Carole's disappearance as a murder investigation.
"I am unable to go into further detail about the nature of the new information at this time. However, we now believe that Carole has not been seen alive since April 16.
"Since that time, significant plundering of her estate has taken place to the value of hundreds of thousands of pounds.
"In addition to a number of fraudulent transactions associated with Carole's bank account, there are also a number of her personal possessions that currently cannot be located.
"I am releasing images of items of Cartier jewellery, identical to that worn by Carole, which are amongst items missing from her personal possessions."
The missing items are a Cartier ring, a white gold bracelet, a yellow gold bracelet and a yellow gold necklace, which are all in the same style.
