A suspected militant from the al-Qaeda linked Asian terror network Jemaah Islamiya (JI), Mohammed Sharif bin Rahmat, 35, has been arrested in Singapore, while a second suspected JI operative, Andrew Gerard, alias Ali Ridhaa bin Abdullah, has been released, Singapore's authorities announced on Friday. Bin Rahmat was detained under Singapore's Internal Security Act, and has been a JI member since 1990, a government statement said. He is alleged to have undertaken physical training with JI and attended an armed conflict training camp run by the Laskar-e-Toiba militant group in Pakistan. Gerard, a Muslim convert was released on 24 October, because he no longer posed a significant threat to Singapore, the government said. He had been detained since January, 2002. He had allegedly been involved in operational reconnaissance work for JI.JI's goal is the establishment of an Islamic state in Indonesia and in other parts of South East Asia. The group, which has considerable support in Indonesia and which is actively recruiting and training new members, according to anti-terrorism experts, is believed to be behind a number of deadly bomb attacks in Indonesia. These include the October 2002 Bali nightclub blasts that killed 202 and whose alleged bombmaker blew himself up during a a stakeout with police in Indonesia this week.
