A BILLIONAIRE investment tycoon who once hosted a shooting party for Prince Harry has been killed after he was thrown from his power boat in the Caribbean. Erik Henriksen, 58, owned a £17million 366-acre stately home in the Cotswolds where the young Royal went pheasant shooting. The Norwegian shipping and energy magnate is believed to have been thrown from a 1,000 horsepower, 34ft speedboat earlier this month in the Cayman Islands. It is understood the businessman - who recently split from his wife Anne - died in hospital after the accident on November 9. His stunning seven-bed mansion, which sits in its own valley in Wotton-under-Edge, Gloucestershire, is currently on the market for £17million. Locals said the "daredevil" loved extreme sports, was known for throwing boozy parties, and used to be friends with racing car driver James Hunt. Neighbour Sean Mills said: "He kept himself very much to himself. We did not know much about him. It's very sad."
