The Mongolian common-law wife of a businessman was granted a Hong Kong work visa based on false information given to the Immigration Department by a senior police officer, the District Court heard yesterday. The former chief of the Forensic Firearms Examination Bureau, Brian John Heard, 56, his friend, Peter John Coomber, 47, and Gonchigsuren Odsuren, 36, face a joint charge of conspiracy to furnish false representations to an immigration officer. All have pleaded not guilty. They are accused of falsely claiming Odsuren was to be employed as a technical author and interpreter at OED Ltd, of which Coomber was the director, between October 5, 1998, and May 10, 1999. OED supplies equipment for examining firearms to the Hong Kong police. Prosecutor Kevin Zervos told the court that it was claimed that Odsuren was fluent in Mongolian, Russian and English and was needed as an interpreter for a consultancy project between OED and the Hong Kong police. After the Immigration Department rejected an employment visa for Odsuren on Feburary 4, 1999, Coomber sent another eight days later, and attached a letter signed by Heard. In the letter, which carried the Forensic Firearms Examination Bureau letterhead, Heard said Odsuren's expertise could not easily be found in Hong Kong. Under ICAC caution, the defendants admitted that Odsuren did not do any translation and had come to Hong Kong to live with Coomber. The trial, before Deputy Judge Peter White, continues.
