In the operation carried out between 5.45pm and 10.30pm, police also uncovered two drug processing laboratories.
They arrested 10 members of the syndicate, aged between 26 and 39, who included seven foreigners.
The drugs were of various types and believed to be cocaine, including in liquid form, and an ephedrine precursor. Also seized were five luxury cars, a motorcycle, RM10,840, a pistol, a watch and a necklace.
Bukit Aman Narcotics Criminal Investigation Department director Mohamad Salleh said the first raid was at a bungalow on Jalan Ampang, which was used as a drug processing laboratory.
He said two Indian nationals, aged 24 and 29, and a 31-year-old Russian, were arrested in the raid.
“During the raid, police also found a certain amount of drugs, believed to be syabu and cocaine, a gun, various chemicals and a paper with a formula on drug processing at the premises,” he told a media conference here today.
Following this, he said police arrested a 31-year-old local man on Jalan Kemajuan, Petaling Jaya.
Acting on a tip-off, they raided a bungalow on Jalan Kemajuan which was also used as a drug processing lab.
Four Indian nationals, aged 26 to 39, were arrested, he said, adding that police also found a certain amount of drugs, suspected to be syabu, and various drug processing equipment at the premises.
“The next raid was carried out at the lobby of a hotel in Petaling Jaya and we detained a local man, aged 30.
“Checks conducted on a vehicle at the hotel car park led to the discovery of a certain amount of drugs and chemicals to process drugs,” he said.
He said a 27-year-old local woman, said to be a girlfriend of the Russian man, was arrested in another raid at an address on Jalan Ampang.
Mohmad said an investigation found the syndicate was believed to be trafficking in drugs into the country and neighbouring countries.
Further investigation found that the Russian man entered the country using a valid work permit, which expires next year. He had entered the country as a student five years ago.
The six Indian nationals were without valid travel documents, he said, adding that all of them were under remand until this Tuesday for investigation under Section 39B of the Dangerous Drugs Act.
