A court in Hanoi sentenced a petrol station's owner to two years in prison for cheating his customers out of VND494 million(US$25,345) on Thursday.
Nguyen The Loc's employee Nguyen Tuan Quang and his nephew Hoang Van Quy, meanwhile, received 18-months in jail and 21-month suspended sentence respectively for the same charge in the largest petrol scam detected so far in the capital.
According to the indictment, Loc, 54, installed a chip in the pump systems of his Hoang Xuan Loc Petrol Station in Tu Liem District with the assistance of Quang and Quy.
The modified systems conned customers into paying for 29,743.5 liters of petrol that they did not recieve from March and July.
The extra petrol amounted to VND494 million.
