Police in Hanoi siezed thousands of bottles of fake liquor and busted a major producer on Monday.
Driver Nguyen Dinh Chieu, 42, was caught while delivering more than 82 liters of fake liquor in 2,520 bottles.
The bottles were branded "Vodka Hanoi," a product of Hanoi Halico Wine Joint Stock Company, a local wine retailer.
Chieu had picked up the liquor from a factory owned by Zuso International Joint Stock Company in Ngoc Son Industrial Zone, on the orders of Zuso director Trinh Van Truong.
Officials from Halico who inspected the seized liquor confirmed that it was fake.
A search conducted at Zuso factory found a liquor production line, empty bottles and labels with Halico's brand "Vodka Hanoi."
Workers at the factory said Truong made them buy "Vodka Hanoi" bottles from the market and print duplicate labels.
They said the director made them produce fake products although Zuso is doing good business, selling two million liters of Vodka Stroka a year, a product the company jointly produces with German group Friedrich Albert von DÃ¶hle, legally.
The fake liquor was mostly produced at night and delivered around northern provinces the next morning.
Zuso also printed fake quality certificates for the liquor, police found.
Nguyen Hong Tien, a marketing official from Halico, said his company notified the police immediately on discovering that Zuso was making copycat products.
Tien said Zuso might have sold a lot of fake liquor for the upcoming Tet, Vietnam's biggest festival.
Several people from the company are being questioned by the police.
Police officer Le Hong Son said this was a huge crackdown on fake liquor producers.
