Chung Hung-wa spent his 10th birthday locked up in a boys' home yesterday as immigration officials prepared to deport him on Monday. The young mainlander came to visit his father, brother and sister, who are all legal residents here, but was picked up for overstaying his two-way permit earlier this month, his lawyer Pam Baker said last night. Even his mother is currently in Hong Kong on a visitor's visa, leaving just a sister whose age is unknown to be with him if he is sent back on the eve of Lunar New Year, she added. Hung-wa is one of three young clients, the others aged eight and nine, being held in Pui Chi Boys' Home in Quarry Bay as Ms Baker and colleagues prepare documents to allow them to stay to fight test cases on their right of abode. 'The most shocking thing is that they are going to remove them on Chinese New Year's Eve,' Ms Baker said. 'What would it cost them to let them stay with their families for New Year and then let a judge decide their case?'
