WARWICK Reid, who has expressed fears over his own safety and been in ICAC custody since March 1990, will serve the rest of his sentence in Correctional Services custody. Reid, 45, who was sentenced to eight years' jail by Chief Justice Sir Ti Liang Yang for corruption, was removed to the security wing of the Siu Lam psychiatric centre on Saturday. According to an ICAC spokesman, the decision to transfer Reid was taken because he was no longer required to give evidence in forthcoming trials. Reid has given evidence in three trials, during which he expressed fears for his safety, saying he would rather be in ICAC custody than in jail. The last trial in which he was to testify was scheduled for April, when Eddie Soh faced a charge of conspiracy to assist Reid escape from Hongkong. Reid had been granted immunity from prosecution in relation to his accepting bribes and for possessing a gun, ammunition and a forged passport provided he gave full and truthful evidence in the trials. But he was accused of ''watering down'' his evidence when testifying against a former colleague, Kevin Egan, and his testimony varied drastically from his earlier sworn evidence. In three of the charges laid against Egan in relation to the flight of Reid, and which were dropped by the Crown, Reid was said to have ensured that an essential ingredient in each had either been removed or greatly diminished. If Reid is found to have breached the terms of his immunity, he may find himself facing more charges. According to the prosecution, Reid's position is under consideration, but no decision has been made. In sentencing Reid in July 1990 for having more than $12 million worth of inexplicable assets under his control, Sir Ti Liang told him that he could petition the Governor after giving evidence for the Crown, recommending that three years be deducted. Should Reid be granted the reduction, he could look forward to being released in July, but a spokesman for the Governor, Mr Mike Hanson, yesterday said no petition had been received from Reid.
