Police investigating the death of oil executive Carole Waugh have arrested a second man on suspicion of murder.
Rakesh Bhayani, 40, of Wembley in north London, is currently being interviewed at a south London police station.
Police say Bhayani, who is unemployed, has already been chargeed with fraud relating to transactions associated with Ms Waugh's identity.
The 50-year-old died of a single stab wound and her body was found in a lock-up garage in south-west London last Thursday.
Miss Waugh, who is originally from Durham, had not been seen by her family since mid-April.
Nicholas David Kutner, 47, of no fixed abode, has been bailed to return to a police station on August 25 after being arrested on suspicion of murder and kidnap last week.
He also faces two charges of renting her property by pretending to be her brother and a fourth of unlawfully withdrawing funds from Miss Waugh's bank account.
Police say 10 people have been arrested in connection with the case.
