The former chairman of a Hong Kong-listed mobile phone company is expected to face public trial in one of Guangdong's biggest tax evasion cases. A news Web site, southcn.com, reported yesterday that Global Tech (Holdings) chairman Johnny Sze Tsang-fai, 43, had confessed to concealing nearly 200 million yuan (HK$188 million) to evade tax. Mr Sze was arrested by Guangdong police last September for the alleged non-payment of 104 million yuan in tax. However, police claim that further investigation has revealed that he concealed more taxable income between 1999 and 2001. Xinhua reported that Guangdong police arrested Mr Sze and seven of his employees last January, and immediately froze a company bank account with a 140 million yuan balance. Mr Sze allegedly hid a total of 1.3 billion yuan in taxable sales from his privately-owned shell companies, Xinhua said. It is further alleged that since 1998, he created two sets of accounts for each of his companies, Guangdong Foshan City Xinlingyu Telecommunications Equipment and Tianfu Telecommunications Equipment. No one from Global Tech, an official dealer for Samsung handsets in Hong Kong, was available for comment yesterday. Mr Sze resigned in February last year, and his brother Timothy Sy took over the chairmanship of the company.
