Christoph von Hohenlohe, a member of one of Europe's most illustrious aristocratic families, was buried yesterday in the southern Spanish resort of Marbella after dying in mysterious circumstances in a notorious Bangkok jail. ........he died earlier this month at the hospital unit of the squalid Klongprem Central Prison in Thailand........ The Thai authorities have so far declined to open an inquiry. Hospital sources have suggested the playboy aristocrat died from a blood infection or insulin deprivation.

Von Hohenlohe was arrested and jailed in Bangkok on 31 July on a charge of falsifying documents. The prince, who had travelled to Bangkok apparently for treatment to lose weight at a luxury health clinic, was due to return home to Hawaii, but was delayed by three days after failing to get on a flight.............As his exit visa had run out, he changed the date in pen so as to avoid more paperwork. .......... he was sent to Klongprem jail. Klongprem has been condemned by the human rights group Amnesty International for its inhumane conditions.

"It is all a bit strange. He was held in a small room with 40 inmates and no mattresses," said Hubertus, who travelled to Bangkok to try to get his brother out of jail.
