Traffickers of Laos timber are blacking out the windows of vans and small buses in order to slip into Vietnam undetected, according to Sunday reports on VietNamNet.
Le Van Thanh, chief forest ranger in Huong Hoa District said that a number of 12-24 seat vehicles have used the ruse slip past guards at the Lao Bao border crossing.
The wood is being trafficked to Dong Ha, a major city in the Quang Tri Province to be sold on black markets.
The rangers have successfully caught four of the vehicles.
Some had local plates and others originated from nearby Thua Thien-Hue. The traffickers had removed the seats from all of the vehicles, Thanh said. The ranger added that he and his men were working against a network of lookouts posted along the route to alert timber smugglers of their presence.
The rangers are asking for help from police and concerned citizens.
In related news, forest rangers in the south central province of Phu Yen stopped a truck on Saturday containing nine cubic meters of wood that is banned from logging, trade and transport.
The driver managed to escape.
