A Vietnamese man wanted for a vicious assault on a woman who reprimanded him for smoking in the lobby of a block of flats in Nonthaburi was arrested on a train while heading out of the country on Thursday.

Lung Van Chuyen, 30, was apprehended on the Bangkok-Nong Khai train at Khon Kaen railway station in Muang district about 3.30am, the tourist police said.

The arrest followed a Facebook post by user Mikke Minne, about a drunken man hitting a woman who reprimanded him for smoking outside his room at the flats in Bang Yai district of Nonthaburi on Dec 4. The post was supported with surveillance camera footage.

The woman, who works in the office, filed a complaint with Bang Yai police and the Nonthaburi Court later issued a warrant for his arrest.

The man was travelling on the train, intending to cross the border in Nong Khai to Laos and then return to Vietnam, police said. Police took him back to Bang Yai for prosecution.
