Three men are arrested as 3,000 bogus bills and two inkjet printers are found in Yuen Long Police yesterday arrested three men for making bogus $500 banknotes in a village house at Yuen Long and seized 3,000 of the fake notes - 12 times more than the number found in Hong Kong last year. The fake HSBC notes were seized along with other unfinished ones, two colour inkjet printers and a small quantity of the drug Ice when officers broke into the house in Nam Pin Wai at 3am. Police said less than 250 bogus $500 notes were seized last year. Chief Superintendent Vincent Wong Fook-chuen, head of the Commercial Crime Bureau, said the latest notes were poor quality and could easily be distinguished from the genuine article. 'The notes had no security features such as watermarks or metal security threads. None had been circulated in Hong Kong,' he said. The raid, involving about 40 officers from the Kowloon West regional crime unit and the Commercial Crime Bureau, was mounted after a tip-off was received several days ago. Three men - a Hong Kong resident, a mainland visitor and a Taiwanese man - were allegedly found printing the notes on A4-size paper and cutting them inside the house. Mr Wong said it was likely the fake notes were intended for circulation outside Hong Kong. The suspects, aged between 32 and 40, were still being held for questioning by the police last night and no charges had been laid. Six police officers were injured by fragments of glass when they broke through the door of the house. They were treated and discharged from Tuen Mun Hospital. New $100 and $500 banknotes with improved security features went into circulation last month, but all existing notes remain legal tender.
