Two Malaysian men have been arrested in Cambodia on charges of attempting to smuggle 2.2 kilogrammes (five pounds) of amphetamines to Kuala Lumpur, police said Saturday.

Wong Ken Kiong, 41, and Wong Koon Ming, 49, were arrested Friday at Phnom Penh International Airport as they went through routine security checks before their planned departure, said Thong Sophat, deputy chief of airport police.

"We noticed that their behaviour did not look normal, and they trembled as they walked through security," he told AFP .

Entered as tourists

A body search revealed that they had strapped the drugs to their thighs and hidden some in their underwear, he added. The two men had entered the country as tourists on Tuesday, he said.

Impoverished Cambodia is becoming an increasingly popular trafficking point for narcotics, particularly methamphetamines and heroin, after neighbouring Thailand toughened its stance on illegal drugs in 2002.
