Ten people have been arrested for trying to sell fake Manchester United merchandise worth about $40,000 ahead of Saturday's soccer match against a Hong Kong squad. More than 50 officers raided 14 street hawkers and two shops in Mongkok, Causeway Bay and Stanley on Tuesday afternoon after a week of surveillance. The three men and seven women, aged between 28 and 59, have been released on bail. About 600 fake Manchester United products with a retail value of $40,000 were seized among 1,800 counterfeit items. Samson Chiu Yuk-hung, head of customs' Trade Descriptions Investigation Division, said the fake products came from the mainland and investigators were trying to trace the source. He said the goods for the British soccer team were badly made and easily identified as fakes. The street stalls were selling fake Manchester United shirts for between $80 and $100, while a genuine team shirt retails for about $500, according to Mr Chiu. 'We believe that counterfeiters target visitors who come to Hong Kong to see the match and they sell the bogus items to make quick cash,' he said, adding that customs would continue to monitor the situation. Those found guilty of counterfeiting face a maximum penalty of a $500,000 fine and five years in jail. Meanwhile, the Hong Kong Football Association said ticket sales for the ING Manchester United Cup on Saturday were going strongly. 'We predict a full house,' a spokesman said. 'Compared to previous experience with other foreign teams, the tickets for this match have been selling at a very satisfactory rate.' By yesterday, about 6,800 of the 20,000 public tickets remained for the match at Hong Kong Stadium. They are selling for $980, $780, $480 and $380. Manchester United arrive tomorrow morning. They are due to make a brief appearance at the airport for the media before going to the Grand Hyatt in Wan Chai. The hotel said enough security was in place for the squad of superstars, which includes Ruud van Nistelrooy, Ryan Giggs and Cristiano Ronaldo. Tomorrow night the team will hold a one-hour open training session at the Hong Kong Stadium. Manchester United will then leave for Beijing on Sunday for the second leg of its four-match Asia Tour.
