London: Investigators were conducting further tests on Wednesday in a bid to shed light on the death of Eva Rausing, one of Britain`s richest women, whose body was found in her west London home.
Her husband, Hans Kristian Rausing, has been arrested in connection to suspected drug crimes and police want to question him about the circumstances of his wife`s death. He is currently receiving medical treatment in a London hospital.
Police have not indicated that Eva Rausing`s death was a result of foul play or that a crime was committed.
US-born Eva Rausing, 48, and her husband were wealthy philanthropists who have both waged a long battle against drug addiction. They were arrested on drug charges in 2008 after Eva Rausing was caught trying to smuggle crack cocaine and heroin into the US Embassy in London in her handbag.
Hans Kristian Rausing, 49, is an heir to the Tetra Pak fortune his father built as a globally successful manufacturer of laminated cardboard drink containers.
Police found Eva Rausing dead at her multimillion-pound (dollar) London home on Monday. Initial post-mortem examinations yesterday failed to establish a formal cause of her death.
The Metropolitan Police said officers arrested a 49-year-old man Monday in connection with the case. Police did not release the man`s name but offered details of the arrest in response to a question about Hans Kristian Rausing.
They said they arrested the man on suspicion of drug possession, and that a subsequent search of an address in London`s upmarket Belgravia neighborhood related to that arrest led to the discovery of Eva Rausing`s body later that day.
Police said he remained under arrest Wednesday but was receiving medical attention at a location away from a police station. They would not say if the man was under guard.
Eva Rausing`s parents, Tom and Nancy Kemeny, and the rest of her family paid tribute to a "devoted wife" and mother of four "much loved and wonderful children," saying they were devastated over her death. Their statement also alluded to her struggles.
"During her short lifetime she made a huge philanthropic impact, supporting a large number of charitable causes, not only financially, but using her own personal experiences," the family said in a statement. "She bravely fought her health issues for many years."
A statement from her in-laws, Hans and Marit Rausing, said they were "deeply shocked and saddened to hear of the tragic death."
