The Ministry of Public Security have arrested five people for allowing overloaded trucks onto a completed section of the Noi Bai – Lao Cai expressway which remains under construction.
The arrestees include Nguyen Hoang Thang and Nguyen Tuan Hoang of the Vietnam Expressway Corporation; Ha Nghia Hanh and Dao Huu Quan of Bridges and Road Construction Group No. 18.6.
The men will be charged with taking bribes.
The other arrestee is Nhu Van Hiep, director of the Hiep Huong Company which owns the trucks, and was arrested on charges of paying the bribes.
Police said that between June and July, Hiep bribed the four other suspects to purchase highway access for his trucks.
Hien confessed that he had overloaded the trucks he sent out onto the expressway with rice and agricultural produce being exported from Lao Cai to China.
The arrestees confessed they were paid VND300,000-1 million (US$14-48) per truck.
Police said the overloaded trucks damaged many sections of the highway and seriously affected the quality and progress of the project.
The Vietnam Expressway Corporation had already complained to the Ministry of Transport about many trucks driving on the expressway, while it was under construction.
The trucks traveled in group and threatened guards who tried to stop them.
Police are investigating the case further.
