Inspector-General of Police Khalid Abu Bakar said this in response to a video featuring the first known Malaysian IS fighter in Syria threatening to ensure Bukit Aman would no longer have peace.

“This is not the first video the group has released. I want to state here that the police will never ever allow IS elements to gain a footing here, or even spread their ideologies.

“Don’t try to threaten us as we are too old for this. We will not take this lightly.

“You only dare to make threats from afar, (why don’t you) come back,” Khalid told a press conference here.

He said although the police would not increase the national threat level, they would be on standby mode and continue to prepare themselves for any possible attacks.

In the propaganda video, three South-east Asian IS fighters in Syria – the Malaysian identified by police as Mohd Rafi Udin from Negeri Sembilan, a Filipino and an Indonesian – took turns to urge IS supporters in their home countries to stage attacks.

The men in the video are believed to belong to IS’ Khatibah Nusantara division, the South-east Asian branch of IS in Syria.

When asked about Special Branch Counter-Terrorism Division chief Ayob Khan Mydin Pitchay’s statement that the police were “preparing for potential attacks within six months by two sources, Khatibah Nusantara in the Philippines, and central IS”, Khalid said it was possible.

“I urge all security forces to heighten their security level, especially in public areas. This is even more important now following the release of the video which is plaguing the public’s mind.”

Rafi in the video called on IS supporters to use any means necessary to “kill” non-believers.

“Kill them wherever you meet them… If you have a car, hit them… Use your weapons and knives to stab them in the chest,” he said.

He said he and his friends in Syria would lend support for such actions from afar.
