HONG KONG drug smuggler Poon Yuen-chung, 22, who was executed in Singapore yesterday, donated her kidneys and corneas to the territory. 'A transplant co-ordinator went to Singapore earlier this week to obtain the consent,' Hospital Authority spokesman Lai King-kwong said. 'Our guiding policy is that the donation must be voluntary and that there is no money payment involved. We will accept organs, even from criminals, if they meet this criteria.' Two other Hong Kong people, Tong Ching-man, 24, and Lam Cheuk-wang, 25, were among five criminals hanged at Changi prison. Poon and Tong were cremated after a funeral service attended by relatives and friends. The Christian pastor who conducted the service said the two women had become close friends in prison. 'Yuen-chung had written more than 40 letters during her last days to her parents, brother, sister and friends to tell them she had accepted her fate with calm and that she hoped to see them in the after-life,' the pastor said. Human rights group, Amnesty International, said it was outraged by the execution. 'These girls were so young, but the Singapore Government would not see that and allow clemency. We will continue to fight for the rights of the people,' Amnesty spokesman Anthony Chiu Sin-wing said. Amnesty submitted a last-ditch appeal for clemency to the Singaporean authorities on Thursday, arguing that Poon, in particular, should have her sentence commuted as she was only 18 when she was arrested. Poon denied she knew that $44 million worth of drugs were hidden in the false bottom of suitcases belonging to her and a travelling companion, who was 17 at the time and was sentenced to life imprisonment. Only those over 18 can be sentenced to death according to Singapore law. Tong was also 18 in 1988, when she and Lam were found carrying $10 million worth of heroin as they passed through Singapore in transit from Hong Kong to Brussels. Britain had also made an appeal for clemency, and the Hong Kong Government said it 'deeply regretted the pleas were unsuccessful'. The other two executed drug smugglers were a Nigerian trader, Chris Chinenye Obaka, 32, and Yeo Hee Seng, 34, an unemployed Singaporean.
