Kuala Lumpur police chief Fadil Marsus said three Malaysians and three foreign women were arrested during the raids conducted between Oct 14 and 17 at condominium units in Kuala Lumpur and Selangor, Berita Harian reported.

A total of 462.5kg of methylenedioxy-methamphetamine (MDMA) powder, better known as ecstasy, was seized, Fadil said at a press conference.

Also seized were 38.7kg of cannabis, 195g of Erimin 5 pills, 52.8g of ecstasy pills, and 32.8g of ketamine.

Other items included cash, bracelets, rings, earrings, watches and valuables.

Fadil said the two syndicates that were smashed used the condominium units as drug storage facilities before distributing the drugs to customers. They also carried out transactions at parking lots.

The first syndicate had been active since February, distributing processed MDMA, while the second syndicate had been operating since September, distributing cannabis around the Klang Valley.
