THE owner of a printing shop accused of possessing enough forged pages to make about 2,000 British Hongkong passports went on trial in the High Court yesterday. Yau Chi-keung, 45, has denied one count each of forgery of documents, possession of forged documents, and possession of documents, equipment and articles fit and intended for use in the forgery. It is the Crown's case that these included 17,016 forged, machine-readable double pages, a printing press, a photo engraving machine and a forged British Hongkong passport in the name of Chui Choung-yin. Opening the Crown's case before Deputy Judge Daniell and a jury, Senior Crown Counsel Tong Man said Yau was the proprietor of a printing shop in Central and employed three staff. On January 17, 1991, the police and the Immigration Department raided the premises. The hearing continues today.
