Razarudin said police are still working on tracking down the suspect by looking for fingerprints on the objects and other related evidence, Harian Metro reported.

“The bomb (placed under Siti’s car) is a serious crime and such a threat is akin to attempted murder. Further investigations are being conducted by the Kuala Lumpur police,” he was quoted as saying.

The IGP added that police were taking “aggressive action” and urged members of the public against speculating on the case.

Last Friday, Siti said she was alerted to two suspicious objects underneath her car after she sent it to a workshop in KL.

She posted a video on Facebook of what looked like plastic water bottles that were attached to the suspension on one of her car tyres, saying: “It looks like a bomb”. A bomb squad was dispatched after Siti called the cops.

Brickfields police chief Amihizam Abdul Shukor later said the objects were believed to be an improvised explosive device (IED), adding that the area in Jalan Maarof, Bangsar, was immediately cordoned off after Siti alerted police.

Meanwhile, Kuala Lumpur police chief Shuhaily Zain said nine witnesses have given their statements over the incident and several CCTV recordings have been obtained.

“We are going through the footage of each CCTV in the areas mentioned by the victim. The case is still under probe.”
