Malaysia has made its largest ever seizure of crystal methamphetamine, officials said Monday, finding nearly 1.2 tons of the drug disguised as tea in a shipment from Myanmar, and arrested six suspected traffickers.

The bust comes as Southeast Asia reports a flood of the stimulant throughout the region. Indonesia and Thailand have also made record seizures of the drug this year.

A total of 1,187 kg of the drug, worth 71 million ringgit ($18 million), was shipped in a container from Yangon, Myanmar, to Port Klang, on the outskirts of Kuala Lumpur, Customs Director-General Subromaniam Tholasy told reporters.
