SINGAPORE - Singaporean Asyrani Hussaini, 24, has been detained for two years under the Internal Security Act (ISA) for attempting to engage in violence in Thailand, the Ministry of Home Affairs (MHA) said on Thursday.
He was detained in March.
Asyrani had sneaked into southern Thailand illegally to link up with Thai insurgents after failing to contact them through other means, said the MHA in a statement. He was unsuccessful and entered another regional country illegally where he was arrested and convicted for immigration offences.
After completing his sentence, he was deported to Singapore and was arrested under the ISA.
Describing Asyrani as "self-radicalised", the MHA said he "was influenced by the radical ideology he had read online".
Another Singaporean, Mustafa Kamal Mohammad, 58, was placed on Restriction Order (RO) for two years from Tuesday.
Under an RO, a person must abide by several conditions and restrictions, such as not changing his residence or employment or travelling out of Singapore without prior approval.
Mustafa was a member of the militant Moro Islamic Liberation Front (Milf) in the Philippines. He had undergone military training at Milf's Camp Abu Bakar and raised funds for Milf.
