Bukit Aman secretary Noorsiah Mohd Saaduddin said the suspects, aged 25 to 34, were detained in raids carried out by the narcotics crime investigation department in Selangor and Kuala Lumpur.

“This syndicate is believed to have been active since the beginning of this year, with its modus operandi of mixing ketamine liquid into vape flavours and using courier services to distribute drugs for the local market,” she said in a statement today.

Noorsiah said of those detained, five tested positive for methamphetamine, amphetamine and benzo. Six of them had previously been involved in drug and criminal activities.

According to her, all seven have been remanded for five to seven days starting yesterday, for investigation under Section 39B of the Dangerous Drugs Act 1952.
