THE Justices of the Peace leading the investigation into the controversial raid at the Whitehead Vietnamese detention centre will call randomly on police and Correctional Services Department (CSD) officers for information. Inquiry secretary Anthony Bennett said yesterday that JPs Andrew Li Kwok-nang QC and Professor David Todd had been working every day since the inquiry was ordered by the Governor on April 14. This week they would interview as many Vietnamese involved in the transfer as possible. ''We are keen to ensure that everyone who has something to say will be given that opportunity,'' he said. ''We have spoken also with the United Nations High Commissioner for Refugees [UNHCR] officer who was in a position to see the raid on the day.'' Two UNHCR officers had been in the camp but only one had been in a position to see anything. ''We spoke with him at length because he was the one person who is not on the side of the authorities or of the Vietnamese,'' he said. A total of 1,250 officers in full riot gear using tear-gas and Mace were involved in the April 7 raid which was to transfer 1500 people in Whitehead's Section 7 to the camp at High Island. Mr Bennett said the two JPs would stay near the detention centres to allow the early starts and late finishes necessary if the June 10 deadline for a final report to the Governor were to be met. ''First priority for interviews has been given to Vietnamese who will soon be returning to Vietnam under the voluntary repatriation scheme. Obviously we want to hear what they have to say,'' Mr Bennett said. Mr Li and Professor Todd also had spent several hours viewing ''about a dozen'' video tapes taken during the raid by police and the CSD. They would review the tapes after the interviews to try to verify information. ''The JPs will also select officers involved in the raid at random to ensure that nothing is missed and people at all levels are dealt with. They will do a similar thing with the Vietnamese population,'' he said. More than 200 people sought treatment for burns and other problems after the raid in which 557 tear-gas canisters were fired. In the Vietnamese detention centres yesterday, widespread hunger strikes continued to protest against the Government's policy of forced repatriation and the screening system used to determine refugee status. About 25,000 Vietnamese boat people remain.
