KUALA LUMPUR — Malaysian police on Friday said they have arrested four more suspected Tamil Tiger separatists, including a man allegedly involved in the attempted assassination of a former Sri Lankan president. The arrests come after three Sri Lankans, including two refugees, were deported in May amid a crackdown on suspected militants, prompting criticism from the United Nations refugee agency. mFederal police chief Khalid Abu Bakar said the latest arrests happened in raids around the capital Kuala Lumpur on Thursday. One of them is believed to have been involved in the attempted assassination of former Sri Lankan president Chandrika Kumaratunga in 1999, while another is a suspected bomb expert, Khalid said. – AFP
