A Singaporean man is being investigated for allegedly going to Syria "with the intention to undertake violence" in the ongoing armed conflict there, said the Ministry of Home Affairs (MHA) in a media statement on Saturday.

Haja Fakkurudeen Usman Ali, a 37-year-old supermarket manager, is a former Indian national who obtained his Singapore citizenship in 2008. A member of the public informed the authorities of his alleged travel to Syria after he had already left Singapore.

MHA also said it was established that Gul Mohamed Maracachi Maraicar, a 37-year-old Indian national and former Singapore permanent resident, had abetted and assisted Haja in his radicalisation and plans to participate in armed violence in Syria.

Gul, who worked as a system analyst with a multinational company here, was investigated under the Internal Security Act and deported and banned from entering Singapore for his role in abetting and aiding Haja.

A spokesman for the ministry said: "We would like to remind the public to alert the authorities if they suspect that a friend or family member has become radicalised or who is planning to undertake armed violence overseas.

"This will enable the authorities to take appropriate action to prevent the person from pursuing acts of violence that could cause harm to himself or others and even lead to the loss of lives."
