SEPANG: Police have arrested two men in separate drug trafficking cases at Kuala Lumpur International Airport (KLIA) and KLIA2, seizing drugs worth more than RM1.6 million.

KLIA deputy police chief Superintendent Albany Hamzah said police detained a 38-year-old Indonesian man at the KLIA arrival hall at 10.15am on March 27 after observing suspicious behaviour.

A search of the man's luggage uncovered five new laptop bags, each containing two black-wrapped packages filled with suspected cocaine, weighing a total of 5,726g.

Albany said the suspect had no prior criminal record in Malaysia, and an initial urine test returned negative.

"The seized drugs, estimated to be worth RM1,145,200, were brought in from Brazil. We believe the supply was meant for distribution outside the country," he said in a statement.

The suspect had hidden the drugs inside new laptop bags to avoid detection. He was initially remanded for seven days until March 3, with the remand extended to March 8 to assist investigations.

In a separate case, police arrested a 48-year-old Malaysian man on March 29 at 8.30am at the KLIA2 departure hall and found 15 plastic-wrapped packages containing crystal-like and powdered substances believed to be methamphetamine, weighing about 15,978g.

"The suspect has five prior drug-related offences and three previous criminal records. A urine test showed positive results for methamphetamine and amphetamine," Albany said.

The drugs, valued at RM511,296, were believed to be intended for distribution in Sarawak.

Police said the suspect had wrapped the drugs in black plastic and used self-check-in services, possibly assuming it would reduce the chance of detection.

He was remanded for seven days until March 5 to assist in investigations.

Both cases are being investigated under Section 39B of the Dangerous Drugs Act 1952, which carries the mandatory death penalty or life imprisonment with no fewer than 12 strokes of the cane if the accused is not sentenced to death.
