Hanoi police have arrested three people and seized about ten tons of fake dietary supplements in the neighboring Bac Ninh Province.
Nguyen Tuan Linh was caught on January 24 when he was carrying 170 boxes of royal jelly capsules imitating an Australian brand in a car.
Subsequent investigation led to the raid of eight stores in Bac Ninh Province where police found 505 cartons and 14 sacks of fake supplements.
Police also seized six machines and many packages and labels used for making knock-offs.
The other two arrestees, Nguyen Thi Hong Lien, 33, and Nguyen Cong Viet, 29, confessed to faking supplements of popular brands to sell from VND200,000-300,000 (US$9.5-14) per bottle.
Police are investigating the case.
It is uncertain what has been used in the making of these fake supplements.
