A former bodyguard of Nationalist generalissimo Chiang Kai-shek was yesterday detained pending deportation immediately after a court ordered his release from prison. Shann Yih-cheng, 78, was briefly released from the dock in the Court of First Instance after winning an appeal against an earlier sentence but was promptly remanded in the custody of the Immigration Department pending deportation to Taiwan. Shann, a Taiwan passport-holder, was arrested in Hong Kong on March 3. He was charged with possessing a false Brazilian passport and unlawfully remaining in Hong Kong. Prosecutors offered no evidence on the passport charge, of which Shann was eventually acquitted. On March 26 Shann pleaded guilty before South Kowloon Court to unlawfully remaining. Magistrate Henry Mierczak jailed him for six months. But Mr Justice Pang Kin-kee released Shann on bail on April 14 pending yesterday's appeal against sentence. Oswald Cheung SC, counsel for Shann on appeal, argued that Shann would not have been prosecuted for unlawfully remaining had he not been charged with the passport offence. Mr Justice Pang reduced Shann's term to allow his immediate release.
