A mainland woman suspected of having conned 15 housewives out of more than $470,000 by selling them fake gold rings has been arrested. Police were last night looking for another woman with whom she is suspected to have operated for the past two months in Tai Po and Sheung Shui. Superintendent Leung King-hang said the pair preyed on housewives in public housing estates and markets. 'They claimed they found the rings in construction sites in China during excavation,' he said. 'The pair offered to sell . . . the rings for between $30 and $200 each.' He said the rings were gold-plated metal. Between March and May this year, 15 housewives were cheated out of $477,600 in Tai Po and Fanling. Mr Leung said in one case, a gold ornament was offered in exchange. Police said the mainland woman, 31, was arrested while trying to persuade a housewife to buy rings on Tuesday. Three fake gold rings were allegedly found on her. She is a two-way permit holder. Police also found more than 100 fake gold rings in a bin nearby on Monday.
