An unemployed mainland mother who visited Hong Kong to take part in an evil-spirit cleansing scam was jailed for three years yesterday at the District Court. Liu Shaorong, 36, admitted trying to swindle a 50-year-old housewife out of her savings for an exorcism ritual in Tuen Mun on October 28 last year. Liu and two female accomplices convinced the victim to fetch HK$207,000 in cash and jewellery worth HK$15,000. But the housewife became suspicious and contacted the police. Liu was arrested but her two accomplices are still at large. She pleaded guilty to a charge of conspiracy to defraud. The court heard she came to Hong Kong with the two women, who asked her to join their scam. Prosecutor Irene Poon successfully sought a 50 per cent enhancement of the sentence to reflect the prevalence of such street-level scams, despite Liu's guilty plea. Defence counsel Raymond Ng said Liu committed the crime out of personal stress. She is a mother of five and had to support a husband suffering from tuberculosis.
