Residents have urged the Whitehead detention centre be closed early after six men used a bed to clamber over 13-metre fences and escaped yesterday. Police are still searching for two of the six - aged in their early 20s - who escaped shortly after midnight. Four unarmed men were captured at a roadblock in Sha Tin. A Correctional Services Department spokesman said a boost in security was unnecessary since it appeared the men made a 'spur of the moment' decision to escape. However, four members of Sha Tin District Board toured the centre yesterday and were shown how the men carried one of the camp's three-tiered beds to the inner fence and used it to clamber over. Board member and convenor of the Concern Group on Whitehead Detention Centre, Lau Kong-wah, said the group was assured all dormitory beds would be welded together to prevent a similar breakout. 'It seems it was very easy,' he said. 'They took a bed outside, bounced on it to get up, then used a wooden board from under the mattress to cross the two fences.' In a meeting with the Security Branch last Monday, the group was told a date would be fixed in mid-June for the camp's closure. However, Mr Lau urged the Government to move refugees to High Island camp in the next few weeks because the late-night breakout had 'extremely disturbed' residents. 'Since there was an escape, we urged them to move all refugees within a few weeks. They said they would consider it because there is capacity at High Island.' However, a Security Branch spokesman would only confirm the closure would occur some time before June 30. Correctional Services Department spokesman Lionel Rodrigues said two guards were slightly injured during a scuffle as the six men made their escape. Thirty staff guard about 1,854 boat people who are in the detention centre awaiting voluntary repatriation to Vietnam. About 2,000 people are kept in High Island detention camp. Mr Rodrigues said the centre was adequately staffed and an inquiry would decide whether the captured men were sent immediately to High Island.
