A notorious international drug baron had his sentence slashed by 13 years yesterday in spite of claims he fabricated evidence to win an early release. Chun Yeung, 41, was originally serving a 32-year jail term for his leading role in a massive syndicate which flooded Hong Kong with 280 kilograms of heroin. After his arrest he fed information to the Narcotics Bureau, Independent Commission Against Corruption and the mainland's Public Security Bureau. The Court of Appeal ordered that his sentence be reduced to 19 years yesterday to reflect the help he had given to authorities. Chun was the star witness in a major drug trial in October where he testified against a businessman accused of running the Hong Kong end of his operation. However, other prisoners came forward to tell the jury Chun had fabricated the evidence while in Stanley Prison. During the trial he agreed that he was helping the prosecution because he hoped to secure an early release from jail, but insisted his testimony was true. The jury rejected his evidence and cleared the man he accused. Mr Justice Benjamin Liu Tsz-ming said authorities did not believe that Chun had been guilty of perverting the course of justice. Only last week, police were hoping to use him to identify a suspect in another case. The judge said Chun's role as an informer had put him and his family in danger. His wife had received nuisance calls and Chun was assaulted in prison. 'We are unable to put him in the supergrass category. But his highly useful information provided to the authorities cannot be overlooked,' he said. Chun had been jailed for 25 years for drug trafficking with an extra seven years if he failed to pay up more than $57 million in illicit profits. Mr Justice Liu slashed the 25-year term to 12 years, but refused to reduce the sentence relating to unrecovered assets. He said drug barons must not be allowed to 'look forward to a life-long fortune' after their release from jail. Chun, who has not repaid any of the money, admitted that his drug syndicate stretched from Burma to China, Hong Kong, Canada and Holland.
