At 4:05 pm on Wednesday, 27 February 2008, the JI leader escaped from the Internal Security Department's Whitley Road Detention Centre where he was being detained. His family were visiting him at the time, and he was being led to a room to meet them when he asked to go to the toilet. He then fled. A massive manhunt comprising personnel from the Singapore Police Force, the Gurkha Contingent, the Singapore Armed Forces, the Police Tactical Unit and the Police National Service Key Installation Protection Unit were deployed in the vicinity of the area immediately after the escape. They were later aided by members of the Singapore Guards and the Singapore Armed Forces Military Police Command, before the operation was wound down over 17 hours later without success in locating the fugitive, who was believed to be unarmed.
