Department director Hussein Omar Khan said this included an international network from the Golden Triangle, Bernama reported.
Police also uncovered an attempt by an international syndicate to establish a large-scale illegal laboratory in Selangor.
Hussein said the biggest success was recorded through “Op Chrysogaster“ on March 2, which saw the arrest of two Malaysian men, aged 28 and 44, and the seizure of more than 3.4 tonnes of drugs, suspected to be methamphetamine.
The drugs, valued at RM170 million, were discovered following two raids in Taman Gembira and Taman Overseas Union Garden in Kuala Lumpur.
Hussein said the drugs were believed to have been brought in from the Golden Triangle for distribution in the Klang Valley and the southern states using rented lorries.
They were also to be smuggled to Indonesia and the Philippines.
He said the market price for methamphetamine in Malaysia is about RM50,000 per kg, but the value could rise to as much as RM200,000 per kg if successfully smuggled to overseas markets.
Both suspects have been remanded for 14 days to assist in the investigation.
The seized drugs are estimated to be capable of affecting up to 17 million users if they had entered the market.
The syndicate is believed to have been active since December 2025.
Hussein said that in another operation on March 2, police raided a warehouse at Subang Industrial Park and found hundred drums and bottles containing liquid and powdered chemical substances, and five drug-processing machines.
“The premises had been rented since 2024 using a false identity, at a monthly rate of RM6,500.
“The laboratory had the capacity to process methamphetamine, synthetic cannabis and etomidate on a large scale,” he said.
In the third raid on March 5, police foiled an attempt by a syndicate to distribute 124.7kg of ganja buds, worth RM10.2 million, using a lorry to collect supplies from the northern part of Peninsular Malaysia, during a raid in Taman Sri Rampai.
Three men, aged between 27 and 38, were arrested around Kuala Lumpur.
