"Some perpetrators were arrested in an apartment in Pluit in North Jakarta," Chief of the National Police General Badrodin Haiti said at the Jakarta Police Headquarters here on Wednesday.
He added that the arrests were made after the police discovered an illicit syndicate of drug traffickers in Central Java.
They nabbed a resident of Hong Kong known by his initial as CD for possession of 10 kilograms of methamphetamine, General Haiti stated.
Based on information from CD, the police later detained two others identified as MW and CT.
While conducting a raid in CTs apartment in Pluit, they found the key to a car, inside which they located 350 kilograms of methamphetamine.
Haiti further noted that the syndicate had most likely smuggled the drugs into Indonesia by means of land, sea and air transportation that had halted in Malaysia.
Moreover, in accordance with existing laws, the perpetrators could face death penalty as well as a minimum fine of Rp1 billion and a maximum of Rp10 billion.
"We will also charge them for breaking laws on money laundering," Haiti pointed out.
The Indonesian police are still trying to find the main perpetrators behind the drug ring. They are known by their initials as ALG and JCK, believed to be still at large in Hong Kong and Thailand.
