A DECORATOR was yesterday acquitted of conspiracy to kidnap a businesswoman after his cautioned statement was ruled inadmissible as evidence. Cheung Hing-wah, 32, represented by counsel Newman Wong, denied a count of conspiracy to kidnap the 39-year-old victim, in December 1991. In his cautioned statement, Cheung admitted partial knowledge of the kidnap plot. The defence submitted that the statement was brought about as a result of police violence. In his judgment, Judge Lugar-Mawson told the District Court that he was not satisfied beyond reasonable doubt that Cheung had made the statement freely. Earlier, accomplice witness Wong Chi-keung had testified for the prosecution in the trial. But when the witness was asked in court to name those who had planned the kidnap, Wong made no specific mention of Cheung. Wong, who was found guilty after trial of kidnapping, was sentenced to one years' jail after appeal.
