SINGAPORE - Authorities seized nine luxury cars, four motorcycles, drugs and cash worth more than S$380,000 in total when they arrested a Singaporean drug lord in Malaysia on Wednesday.

The cars included two BMWs, one Mini Cooper and an Audi. Three of the nine cars were Singapore-registered vehicles, Johor police revealed at a press conference on Sunday. Drugs seized include heroine, ketamine, methamphetamine or ice. The cash, in both ringgit and Singapore currency, amounted to over S$19,000.

In the Feb 4 operation around Johor Baru covering five different locations, Malaysian cops also arrested eight other suspects in their 20s and 30s, including another Singaporean.

Johor police chief Datuk Mokhtar Mohd Shariff said that the crippling of the Malaysian-based syndicate was a joint success achieved with the Central Narcotics Bureau (CNB), which had supplied the information on the syndicate activity around Johor Baru, Malaysia newspaper The New Straits Times reported.

He added: "This success reflects the close working relationship between Malaysia and the Singapore police force in busting drug dealing activities along both countries' borders."

The 46-year-old unnamed kingpin is believed to be one of the biggest suppliers of drugs to the Republic.

He is currently remanded in Malaysia and will face the death penalty if convicted.

He allegedly ran a syndicate that could deliver an estimated 4.5kg of heroin and about 500g of methamphetamine or Ice, among other drugs, to Singapore every week. This is enough for more than 2,000 drug abusers.

The CNB said on Friday that the syndicate had been under investigation since December 2012. Investigations are ongoing.
