Illegal immigrants would be too scared to seek medical care after the arrest of a 92-year-old woman in a hospital casualty ward, said a group fighting against the splitting of families. The woman, Lam Ying, was arrested at Princess Margaret Hospital when her immigration status became known and is now in Victoria Detention Centre awaiting repatriation. Sze Lai-shan, a social worker for the Society for Community Organisation, said: 'I have never heard of someone this old arrested for illegal immigration.' She said illegal immigrants were being arrested in hospitals even if they were only visiting other family members. Lam was born in 1905, seven years before the fall of the Qing Dynasty and lived in Heifeng village, the home village of eight-year-old Chung Yeuk-lam who was repatriated last month. Neighbours said they believed Lam came to Hong Kong two years ago to help rear her grandchildren. She went to hospital for treatment on May 18 and was arrested immediately. However, she was allowed to remain for treatment and was taken to Victoria Detention Centre in a wheelchair on Saturday when judged well enough for release. Because she is not a legal resident, she will be asked to pay medical bills of at least $44,000. Her medical complaint is not known. Lam's two sons were initially arrested for aiding and abetting an illegal immigrant, but were released unconditionally after being given a verbal warning, a police spokesman said. At the family flat in Lai King Estate, Kwai Chung, Lam's four grandchildren said their father had gone to China to prepare for her deportation and they did not know when he would return. 'I would like to visit Ah-ma in Victoria Detention Centre,' said the youngest, surnamed Yu and aged 11. Miss Sze said arrested immigrants such as Lam ought to be able to appeal against forced repatriation on compassionate grounds. Officers from the Immigration Department could not be reached for comment.
