Eva Rausing death: Kemeny family pays tribute
The family of one of the UK's richest women has paid tribute to her after she was found dead at her west London home.
US national Eva Rausing, 48, a member of the family behind the Tetra-Pak cartons empire, was found at Cadogan Place, Belgravia, on Monday.
It is understood a man arrested in connection with the death and on suspicion of possessing drugs is her husband Hans Kristian Rausing, 49.
Her parents Tom and Nancy Kemeny said they were "deeply saddened".
Mrs Rausing's death is being treated as unexplained, Scotland Yard said.
A Metropolitan Police spokesman said the man arrested in connection with the death was no longer at a police station and was currently receiving medical attention.
In a statement, the Kemeny family said: "Eva was a devoted wife for 20 years and mother of four much-loved and wonderful children.
"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.
"She bravely fought her health issues for many years. The family is devastated at her death and asks to be given privacy at this difficult time."
The couple's family has previously said the pair had battled to overcome drug addiction and they were said to have donated millions of pounds to charities involving drug awareness and addiction prevention.
Mrs Rausing was the UK patron of international drug abuse prevention charity Mentor and the couple also provided financial backing to Action on Addiction.
Mr Rausing's parents and family added in a statement: "Hans and Marit Rausing and their family are deeply shocked and saddened to hear of the tragic death of their daughter-in-law Eva Louise Rausing.
"They ask that their privacy be respected at this sad time."
A post-mortem examination at Westminster Mortuary did not establish how Mrs Rausing died and further tests are being carried out.
The Met said officers from its Homicide and Serious Crime Command were investigating her death.
Police said they searched the address and found the body after making a drugs arrest on Monday.
Officers could be seen guarding the front door of the Cadogan Place home, which was taped off.
The large terraced house is in one of London's most expensive areas just off Sloane Street, between Knightsbridge and Chelsea.
In 2008 Mrs Rausing and her husband Hans Kristian Rausing faced drug charges after crack, heroin and 52g of cocaine were found in their home.
Mrs Rausing had been arrested after she allegedly tried to smuggle small amounts of crack cocaine and heroin into the US embassy in London.
Charges were then dropped and a caution issued instead.
In 2010 Forbes ranked Mr Rausing's father, Hans Rausing Senior, as the 64th richest man in the world, worth an estimated $10bn (£6.45bn).
The family made their fortune from the Tetra Pak milk carton, patented by Ruben Rausing in 1946. Tetra Pak is a part of the Tetra Laval Group.
