Police in Da Nang on Monday arrested three local men for stealing a bag from a Chinese tourist with his passport and money inside.
Li Jing Ming, 62, found out he lost his bag during a group tour in the central city on Sunday afternoon.
Three men, 39, 46, and 48 years old, were arrested Monday night and they have all admitted to stealing the bag.
Li reportedly left his bag in front of a hotel on Nguyen Van Linh Street before checking in. When he came out, the bag was gone.
They have returned the bag that contains a passport, a credit card, a tablet and cash worth US$300 to the tourist.
Earlier this month, a 27-year-old man in Hanoi was caught by locals and brought to the police after he tried to snatch a bag from a Belgium tourist.
The 57-year-old tourist was walking on a downtown street while the robber approached him from a motorbike and snatched the bag from his hand.
As the tourist tried to seize it back, passers-by stopped the robber, news website Zing reported.
Vietnam has been making various efforts to promote tourism. Foreign arrivals to the country increased 16 percent in the first two months, compared to the same period last year, largely thanks to the 15-day visa waivers offered to tourists from many Asian and European countries.
But at the same time, many tourists say they feel discouraged by reports of street crimes, especially in large cities.
