Hanoi police are looking for a driver who reportedly hit and dragged a traffic police officer for 20 meters with his truck on Saturday morning.
The incident occurred at around 9:50 a.m. on Saturday at the intersection between Sai Dong and National Highway No. 5 in Long Bien District.
Lieutenant Nguyen Quoc Dat, 31, attempted to stop the driver after the truck collided with a car.
The driver did not stop and drove straight into the officer.
Photos showed the officer was bleeding and his uniform was torn after being dragged on the street.
Dat is being treated at Viet Duc Hospital where doctors said he suffered from multiple injuries and had breathing difficulties.
Based on the number plate of the truck in a photo taken by locals, police said it belongs to a furniture company based in the northern province of Hung Yen.
The investigation continues.
