The Rausing family have been left “deeply shocked and saddened” after Eva Rausing was found dead in her London home.
Her husband, Hans Kristian, 49, whose grandfather founded the Tetra Pak empire, was arrested in connection with her death and is now in a London hospital.
Officers discovered 48-year-old Eva’s body after searching the couple’s London home, following Hans Kristian’s arrest for suspected drug possession on Monday morning.
Further tests on Eva’s body have been ordered after a post-mortem was inconclusive.
Hans Kristian, whose father Hans Sr transformed the family’s small Swedish company into a multinational giant, is expected to remain in hospital for “a matter of days”.
"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,” a statement from his family said.
Sweden-native Hans Sr and his brother Gad together ran the family business for years, turning it into a multi-billion-dollar company. Their father, Ruben Rausing, started Tetra Pak in 1951 as a subsidiary of Akerlund & Rausing.
In 1995, Hans Sr, who lives in England, sold his shares to his brother for a reported £3.5 billion (€4.4 billion). The company is privately owned by Gad’s family through the Swiss-based holding company Tetra Laval.
Hans Kristian and Eva met at a drug addiction clinic in the US 25 years ago, and had been active philanthropists particularly when it came to addiction-related charities.
However, their own addition problems became public in 2008 when Eva was arrested after trying to smuggle Class A drugs into the US Embassy.
