Customs officers have uncovered $5.5 million worth of counterfeit jewellery - including items from a 'No Fakes' shop - in the city's largest seizure of its kind. Officers raided two offices and eight jewellery shops targeted at tourists in Kowloon Bay, To Kwa Wan and Tsim Sha Tsui, seizing 450 pieces from five of the shops. The goods included rings, earrings, necklaces, pendants and bracelets allegedly by Fendi, Cartier, LV and Chanel. Four men and seven women aged between 30 and 57 were arrested. They included a company director, shop managers and sales staff, who were released on bail of between $3,000 and $100,000. The head of the Intellectual Property Investigation Bureau, Senior Superintendent Tam Yiu-keung, said it began its investigation a month ago after a complaint from a member of the public about jewellery shops selling fakes. The subsequent investigation uncovered three jewellery companies selling fake goods at some of their branches. About 90 per cent of the seized goods came from two shops in To Kwa Wan and Kowloon Bay, each covering more than 20,000 sq ft and aimed at mainland tourists. They were less than 10 per cent of the total goods on sale. Mr Tam said the shops were selling the fakes for between $2,000 and $60,000, several times cheaper than the genuine goods - and they hoped to attract brand-conscious mainlanders during the National Day celebrations. 'Customs has already contacted the jewellery trade association to further alert them to possible business malpractices and to seek their co-operation in boosting respect for intellectual property rights within the trade,' Mr Tam said. The department urged people to buy brand jewellery from major jewellery companies. Ironically, the To Kwa Wan shop was a member of the Intellectual Property Department's 'No Fakes' pledge scheme, under which companies promise to refrain from selling and dealing in counterfeit and pirated goods. Jenny Wong Siu-ling, the department's community relations manager, said the shop was immediately stripped of its 'No Fakes' membership. 'This means we have taken away their 'No Fakes' stickers and labels. We will also ensure that they will not be allowed to rejoin the scheme,' she said. Hong Kong Jewellery Manufacturers' Association chairman Li King-hi said he hoped the incident would not undermine the trade's overall reputation, especially near the National Day holidays.
