Two Singaporeans were arrested in July for their involvement in terror-related activities.
This was revealed by the Home Affairs Ministry today.
24-year-old Imran Kassim issued with an Order of Detention for intending to undertake armed violence overseas.
MHA said Imran was radicalised by the violent propaganda of Islamic State (IS), and that he had tried to make his way to Syria to join IS on at least two occasions – in 2014 and 2015.
Imran also admitted that he was prepared to attack Singapore Armed Forces (SAF) personnel deployed in the global coalition to fight IS, or hold them hostages to demand ransom from the Singapore Government.
MHA said that his pro-militant views drew attention and eventually someone close to him reported him to the police.
Meanwhile, 23-year-old admin assistant Shakirah Begam Abdul Wahab was issued with a Restriction Order for initiating and maintaining contact with foreign terrorist fighters.
She apparently enjoyed the attention lavished on her and not because she was deeply radicalised.
MHA said had Shakirah actively initiated online contact with IS foreign fighters operating in the conflict zone, after learning of their activities from mainstream media reports and online sources.
She came across social media details of a foreign terrorist fighter and decided to initiate contact with him.
Over time, she expanded her online contacts to several other foreign fighters
