According to the activities on his Facebook page, Zulfikar Mohamad Shariff's religious inclinations had been skewered towards the far right spectrum for years.
Though the 44-year-old moved to Australia with his family in 2002, his radical views on Singapore remained, openly supporting the Islamic State (re: the picture above, where he's seen with his children mimicking the jihadi pose) as well as other hardline groups.

Pretty far down it seems — the man has since been detained under the Internal Security Act for terrorism-related activities. He has been served with an Order of Detention for a period of two years, according to the Ministry of Home Affairs.
