A bogus chain letter claiming to be raising money to save the life of a sick seven-year-old girl is being circulated by e-mail in Hong Kong. The message says 'Amy Bruce', whose family cannot afford her medical bills, will receive seven cents from worldwide charity the Make a Wish Foundation every time the letter is passed on. But the foundation, which for 20 years has been granting wishes to children with life-threatening illnesses, says the letter and others like it are a time-wasting hoax. The chain letter says: 'I am seven years old and I have severe lung cancer from second-hand smoke. 'I also have a large tumour in my brain from repeated beatings. The doctors say I will die soon and my family can't pay the bills.' The letter urges recipients to pass on the message and threatens those who do not with the warning: 'For those who don't send it, what goes around comes around.' Two weeks ago, the South China Morning Post reported that another hoax e-mail was warning Hong Kong mobile-phone users that their handsets would be destroyed by a virus if they answered certain calls. The Make a Wish Foundation said the Amy Bruce message - and a similar one claiming to be from a young boy - was bogus and that the Internet service provider of the person starting the chain had been asked to take action. A spokesman said foundation offices around the world received hundreds of calls each day from people checking the authenticity of fake chain letters linked to the charity. 'The time and expense required to respond to these inquiries distracts the foundation from its efforts on behalf of children with life-threatening illnesses,' the spokesman said. 'More importantly, it divulges information that is potentially harmful to a child and his or her family.' The foundation said computer users should be aware of other chain letters claiming links to the charity. Among them is a letter urging people to send Christmas cards to a sick five-year-old girl, Paige Lane, in the United States. The girl has never asked for cards but has been inundated.
