Perak police chief Yusri Hassan Basri said the three, aged 37 to 42, were attached to the traffic investigation and enforcement department of the Perak contingent police headquarters.

“They have been remanded for three days until Feb 1 to assist in the investigation,” he said in a statement.

Yusri added that Bukit Aman’s classified crime investigation unit had taken over the probe from the Perak police.

The case is being investigated under Section 384 of the Penal Code for extortion, Section 17(a) of the Malaysian Anti-Corruption Commission Act 2009 for giving or accepting gratification, and Section 233 of the Communications and Multimedia Act 1998 for improper use of network facilities.

Yusri also urged the victims to come forward and cooperate with the police to expedite the investigation.

The incident came to light after the British couple shared a clip of the incident on social media.

Posted by the couple on their YouTube channel “TREAD the globe”, the video shows a traffic policeman accusing them of driving at 80kph in a 60kph zone, and saying that he had to issue them a summons.

He then offered to “reduce” the RM300 summons, which he said could be paid at a police station, to an on-the-spot “fine” of RM100.

The couple were seen expressing confusion about whether they were speeding, but agreeing that it was better to have paid the “discounted summons” than to go to a police station.
