A tuk-tuk driver who led a blockade of a Grab taxi at Chiang Mai International Airport on Monday has no public-transport driving licence and will face several charges following the incident, which was exposed by a foreign visitor, police said on Tuesday.

A 65-year-old man drowned after his tuk-tuk tricycle flipped and fell into a roadside ditch in Samut Songkram's Muang district late on Sunday night.
