LONDON - The American wife of an heir to the Tetra Pak carton fortune was found dead in London, police said on Tuesday, and a man who may be Eva Rausing's husband was arrested in connection with her death and on suspicion of drugs possession.

Police described the arrested man only as being 49 years old, the same age as Hans Kristian Rausing, the London-based philanthropist son of Swedish packaging billionaire Hans Rausing, one of the world's richest men.

British media said the arrested man was "believed to be" the younger Rausing, and that he had been arrested after a search of the couple's home in the wealthy Belgravia district where Eva Rausing, 48, with whom he had four children, was found dead.
