Border guards in Nghe An Province on Sunday morning arrested a man suspected of trafficking 6.6 kilograms of heroin from Laos into Vietnam. Ha Ba Cu, a 23-year-old Nghe An native, was arrested in a jungle at the border between the two countries 20 minutes after midnight on Sunday. Cu said he migrated to Laos’ Bolykhamxay Province in 2011 and had smuggled heroin to Vietnam several times since then. Colonel Nguyen Truong Thi, anti-drug chief at Nghe An Border Guards, said his team had followed Cu for “many” months before the arrest, which was part of a “complicated” operation. The border guards are cooperating with the police to investigate further, Col. Thi said. Vietnam has some of the world’s toughest drug laws. Those convicted of producing or selling 100 grams of heroin or 300 grams of other illegal narcotics face the death penalty. Smuggling more than 600 grams of heroin or more than 2.5 kilograms of methamphetamine is also punishable by death. But heroin smuggling from Laos has become more rampant of late, with many arrested and sentenced in court in every recent year.
