Police investigating the death of oil executive Carole Waugh have arrested a woman on suspicion of conspiracy to defraud.
Miss Waugh, originally from Durham but living in London, had not been seen by her family since mid-April before her body was found inside a car at a garage in Lime Court, New Malden, in south-west London, on August 2.
She had suffered a single stab wound.
Scotland Yard said last night the 61-year-old woman was in custody at a south London police station.
Ms Waugh was reported missing by her family on May 7, having last been seen at a family party in mid-April.
So far, 11 people have been arrested in connection with the inquiry. At least three women have tried to pose as her since she vanished, police said.
A second man was arrested on suspicion of murder on Thursday and was last night still being questioned by police.
Rakesh Bhayani, 40, of Chamberlayne Avenue, Wembley, also faces three charges of conspiracy to commit fraud by false representation worth about £280,000, after transactions associated with Ms Waugh’s identity and is due in court next month in connection with those.
The other man, Nicholas David Kutner, 47, of no fixed abode, was arrested on suspicion of murder and kidnap last week.
He also faces two charges relating to renting her property at Tressard Court and a fourth of unlawfully withdrawing funds from the 50-year-old’s bank account.
Kutner is also accused of pretending to be Chris Waugh, Ms Waugh’s brother, in an attempt to sell her London home. He will appear at Southwark Crown Court on Monday on that charge.
Scotland Yard has appealed for information about the blue Volkswagen Golf Ms Waugh was found in, which has the registration number W466 NHL.
