Kuala Lumpur police chief Fadil Marsus said the 29-year-old man was arrested by a team of officers from the city narcotics criminal investigation department at the lobby of a condominium in KL South on Aug 20.

He said police seized a plastic bag containing two compressed lumps of suspected heroin base, weighing 741.5g.

Following the arrest, the suspect led police to a car parked in Taman Segar, Cheras, where they found a sack and a cloth bag containing eight compressed blocks of suspected heroin base, weighing 3kg, and 20 packets of Chinese tea suspected to be laced with methamphetamine weighing 20.5kg in the boot.

Fadil said the total amount of drugs seized, estimated to weigh 23.74kg, was worth about RM974,000 and could supply a single dose each for 420,400 addicts.

He said the syndicate, which had been active since October last year, used cars to store the drugs before distributing them.

The suspect, who has a previous conviction for cheating, has been remanded until Aug 27 and is being investigated under Section 39B of the Dangerous Drugs Act 1952 for drug trafficking.
