Eva Rausing, 48, was found dead in her London home by Metropolitan Police on Monday as one of Britain’s richest men is being held in connection with the death of his American wife.
A post-mortem held today at Westminster Mortuary did not establish a formal cause of death, the Daily Mail reports.
The arrest of Hans Kristian Rausing, 49, on drug charges had prompted police to search the couple’s residence, the spokesperson said.
Metropolitan police did not name Hans Kristian Rausing.
However, they confirmed a 49-year-old man had been taken into custody regarding a woman’s death and possession of drugs.
Officers stood guard outside the home today.
Hans Kristian Rausing, who is Swedish, is the heir to the Tetra Pak food packaging empire. His father, Hans Rausing Sr., has an estimated net worth of $10 billion, according to Forbes’ 2010 rankings.
Rausing was held at a south London police station, but is now receiving medical treatment for an undisclosed ailment. Police declined to further discuss the situation.
The couple had previously been in trouble for possessing drugs.
They were arrested in 2008 after Eva Rausing allegedly tried to sneak drugs into the U.S. Embassy in London.
Officers searched the couple’s home where they found crack, heroin and cocaine.
The couple was issued a formal caution, and the charges were dropped.
At the time of the embassy incident, Eva Rausing told reporters that she was ashamed of her actions.
“I hope in due course to get back on track,” Rausing reportedly said at the time. “I am sorry for the upset I have caused.”
