AN illegal immigrant who evaded authorities for 13 years is finally on her way back to China. Beautician Lo Mei-kuen, 40, will be repatriated immediately following a successful appeal yesterday against an 18-month term. Mr Justice Jerome Chan said in the High Court it was an 'exceptional and unique case' - no other II had been caught after such a long time. Lo, the daughter of a former Kuomintang general, came to the territory in 1981. For 13 years she gave immigration officials the slip with a fake identity card onto which her photograph had been transposed. Her luck ran out in May when she was stopped by police during an ID check at Mongkok MTR station. Magistrate John Meredith jailed her for 18 months for using a forged card and 15 months for staying in Hong Kong illegally, after she had admitted both offences at North Kowloon Court on May 12. But yesterday, Lo's counsel, Gerry McCoy, asked Mr Justice Chan to reduce the sentence because her father was very ill. He also argued it was unfair to jail Lo because the practice in 1981 when she committed the offence was simply to repatriate IIs. The court heard that Lo's father had been persecuted by the authorities after he was stranded in China. Although he was now allowed to return to Taiwan, he had had both legs amputated and needed his daughter to help him move.
