UK police: Heir's wife found dead at London home

One of Britain's richest women, US-born Eva Rausing, was found dead in her west London home and a man was arrested in connection with the case, British police said, adding that an autopsy had failed to uncover a formal cause of death.

Rausing, 48, was the wife of Hans Kristian Rausing, heir to the TetraPak fortune his father built by creating a successful manufacturer of laminated cardboard drink containers.

Both Rausing and her husband had long-running and often public battles against addiction, including her arrest in 2008 for reportedly trying to bring drugs into the US embassy in London.
