The Commercial Crime Bureau (CCB) is considering taking further action against former Pacific Ports chairman John Chan Boon-ning in relation to an alleged $81.1 million theft and other matters, according to police sources. Theft charges against Mr Chan were dropped three months ago in the Eastern Magistrates court after the CCB failed to make sufficient progress in its investigations. However, sources said further evidence had been gathered during the past three months in relation to the alleged theft and other allegations such as illegal share trading. 'The prosecutor did leave open in June the possibility of a re-charge in the future,' one source said. 'We have got evidence involving other allegations and we want to put all the trials into one.' In March, Mr Chan was arrested for allegedly stealing $81.1 million in three company cheques between January 20 and 23. Sources said Mr Chan had personally taken heavy positions in share investments during the market's sharp correction in October. His arrest prompted him to step down as chairman of Pacific Ports and remove himself from daily operations at Pacific Ports' former parent company Fairyoung Holdings. But at the time he retained the chairman's title at Fairyoung. It also triggered the eventual sale of Fairyoung's 43 per cent stake in Pacific Ports for about $415 million to New World Infrastructure and a company linked to Macau gambling magnate Stanley Ho Hung-sun. Mr Chan, a controlling shareholder of Fairyoung, has been pursuing resumption of an active chairmanship of the company since the charges were withdrawn. A spokesman for the company said yesterday: 'We're still seeking legal advice over the resumption. The board of directors have yet to make any decisions.' Mr Chan, who did not return calls seeking comment, is the son of the late Chan Kee-hwa, who was one of Hong Kong's most prominent entrepreneurs. Mr Chan said in June that he was eager to get back to work especially at Fairyoung. However, he has been the target of civil litigations ranging from claims of misusing company funds to breaching fiduciary duties. Pacific Ports has been the most active plaintiff in the litigation, claiming $130 million from him. Apart from claiming the money Mr Chan was alleged to have stolen from Pacific Ports, the company has also alleged he misused its money without approval, buying a Mercedes-Benz and renting a house in Deep Water Bay Road for his own use. Mr Chan's financial problems came to light shortly after he was arrested in March when finance company Pacific Foundation Finance filed separate writs against Fairyoung, Mr Chan's wholly owned trust Angklong, and a company formerly owned by his late father, Kian An Realty, for a combined $142 million in unsettled loans. Mr Chan has his 59.2 per cent stake in Fairyoung pledged to finance companies such as Tai Fook Finance. Fairyoung shares closed yesterday down 4.1 per cent at 38 cents.
