Hanoi (AFP) – Five men were arrested in Vietnam for allegedly attempting to smuggle $2.5 million worth of heroin into China after police shot at their drug-packed vehicle as they tried to flee, Thanh Nien newspaper reported yesterday. The men were caught in northern Cao Bang province on the border with China with nearly 100 kilograms of heroin from Laos in their truck. Vietnam is a key trafficking hub for narcotics from the “Golden Triangle” covering Laos, Thailand and Myanmar. The latest bust is one of the largest in Vietnam in recent months. Five Vietnamese men were arrested between Friday and Saturday as they tried to drive past police in the northern province, prompting “authorities to open fire”, Thanh Nien reported. The bust follows a similar seizure last month in northern Vietnam, where police confiscated 170 kilograms of heroin worth $3 million also from Laos.
