HANOI: Vietnam has arrested 17 people after a blitz on drug crime uncovered major stashes of heroin, cannabis and precursor chemicals, state media said Monday. Six Vietnamese were arrested in Hanoi after being caught with some 120 kilograms (265 pounds) of heroin hidden inside household gas canisters, the Thanh Nien newspaper said on Monday. Eleven more people were arrested in a separate operation targeting drugs being smuggled into Vietnam from Laos, the state-run Vietnam News reported. Some 5.5 tons of precursor chemicals and cannabis were seized during the raid, the report said. Communist Vietnam has some of the world’s toughest drug laws. Anyone found guilty of possessing more than 600 grams (20 ounces) of heroin, or more than 20 kilos of opium, can face the death penalty.
