Locals and police in Hanoi arrested a taxi driver who snatched a mobile phone from a Finns tourist on Thursday night.
Nguyen Xuan Viet, 23, was arrested for stealing an iPhone from a passenger named Mari Susanna.
Susanna, 48, and her husband hailed Viet to take them from Hai Ba Trung street to their hotel in Nghi Tam street.
At their destination, Viet asked the couple to pay him a total of VND 200,000 (US$10), although the taxi meter only read VND 80,000 ($4).
The couple paid him the fee displayed on the meter and left the taxi.
Viet followed the couple for a while before jumping out of his cab, snatching an iPhone out of Susanna's hand and returning to the driver's seat to make his getaway.
A group of good samaritans and local police quickly surrounded the cab and arrested him.
