Governor Chris Patten yesterday promised to review sympathetically the case of a disabled child who faces deportation to the mainland before he can complete medical treatment. Mr Patten said he would be getting a full report from the Immigration Department after receiving a petition from the 13-year-old boy's mother. The case raised difficult issues but it was clear some medical conditions were better treated here than on the mainland, he said. Law Wang-pui has walked with a limp since injuring his left leg in a traffic accident in Guangzhou when he was four. He is visiting Hong Kong under a two-way permit which has been extended, but his parents have been told he will have to leave at the end of next month. Wang-piu is taking regular physiotherapy treatment at Prince of Wales Hospital and is due to receive further treatment there in June. His family, all Hong Kong residents, live in Tuen Mun.
