Mohamad Fadzullah Abbul Razak was taken into custody at his home in Kuala Lumpur on Thursday under the Internal Security Act, which provides for indefinite detention without trial, said Nalini Elumalai, a rights activist who monitors arrests under the act.
The Star newspaper, citing unidentified security officials, described the 28-year-old engineer as one of Malaysia's most wanted terror suspects. He had recently returned from a trip to Thailand, but the reason and length of his visit were not known, Nalini said."
