As authorities continue to investigate the death of Eva Rausing, her husband, Hans Kristian Rausing has been taken into custody in connection with the homicide.
According to the Associated Press, Metropolitan Police arrested a 49-year-old man on Monday in connection with the case, but did not release the man's name.
Police reportedly told the news outlet that they arrested a man on suspicion of drug possession, and that a subsequent search of an address in London's prestigious Belgravia neighborhood related to that arrest led to the discovery of Eva Rausing's body later that day.
The identity of the man was later revealed to be Hans Kristian Rausing, the heir to the TetraPak fortune. Reports indicate that Rausing remains under arrest but is receiving medical attention at a location away from a police station.
Police found Eva Rausing dead at her Belgravia, London home on Monday, July 10. Initial post-mortem examinations on Tuesday failed to establish a formal cause of her death, according to the Associated Press.
Rausing and his wife, whom he met in a rehab clinic in the United States, both reportedly suffered long battles 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 U.S. Embassy in London in her handbag.
Eva Rausing, formerly one of Britain's richest women, was a businesswoman and a member of the Rausing family, which owns the food packaging business Tetra Pak. On July 10, she was found dead at her home in Belgravia, London.
The 49-year-old was heir to the TetraPak fortune was arrested on Wednesday, July 11, in connection with her death and on suspicion of drugs charges.
Eva Rausing's parents, Tom and Nancy Kemeny, have commented by saying that they were devastated over their daughter's death.
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.
