Nguyen Duc Binh, a resident of northern Bac Ninh province, was arrested by Hanoi Police on October 24 on suspicion of selling counterfeit foodstuffs.

On October 15, Binh, 30, was detected driving a small truck with 159 counterfeit bottles of soy sauce bearing the labeling of the Japanese Kikkoman brand.

Binh admitted that since September he has sold the soy sauce, bought from a Chinese at border gates in Lang Son and Quang Ninh provinces, to Japanese restaurants based mainly in the south.

Samples of the sauce have now been taken for testing to see if they contain any toxic additives or other harmful substances.-VNA
