HONG KONG (Reuters) - A British man committed suicide in Hong Kong during a four-day-long stock market crash, police said on Thursday, and a newspaper linked the death to the share slump. The 43-year-old man, whom police declined to identify, was found dead by his wife in their home in expensive Repulse Bay on the south side of Hong Kong island on Wednesday, police said. The man had left a suicide note, but the police spokeswoman declined to reveal the contents of the letter. The Sing Pao daily, a Chinese-language newspaper, said the Briton was a senior executive at a financial institution and that his death was related to the stock market collapse. But police told Reuters it was too early to say whether his suicide was brought on by the financial markets crisis. Hong Kong's blue chip Hang Seng Index has been in free fall since Monday, losing one third of its value in the territory's worst ever share crash.
