Police in the central province of Quang Nam said Thursday three Iranian men who robbed a local filling station early this month are being detained awaiting trial.
On Dec 1, Lalia Mostafa, 24, together with Farhad Hosseininasbardi, 27, and Setoodeh Mohamad Shiraz, 28, stopped their car at a petrol station in Quang Nam's Hoi An Town to buy a can of motor oil.
Farhad then gave the station's staff a VND500,000 note to get a VND200,000 note in change.
Since the staff didn't have the required change, he took the three men to meet the station manager Tran Van Ban to get it.
While Farhad distracted the staff by asking about motor oil cans, his accomplices grabbed a stack of VND200,000 notes that Ban had just taken out. The stack was worth nearly VND30 million ($1,428).
The trio then escaped in the car, heading for Hanoi.
However, they were arrested by traffic officers on arrival at Thua Thien Hue, where police were informed of the robbery by Quang Nam's police division.
Police said the three men entered Vietnam in August and hired a car in Ho Chi Minh City at $90 per day to commit robberies.
They had successfully robbed VND61 million ($2,900) in Dak Lak and Hau Giang Provinces using similar tricks.
