Three Thai tourists were injured after being attacked by a pair of trouble-making youths at Dongtan-Jomtien Beach in Pattaya.
Anansak Chaiin, 48, Wiriya Promnin, 27, suffered minor injuries and swollen faces, while Chatchawal Sinmasud, 43, sustained a serious cut to his hand in the Jan. 27 incident.
Other beachgoers reported two shirtless men riding a motorbike around the Dongtan Beach area harassing and attacking people randomly.
Anansak said the three men were drinking alcohol at the beach when a group of youths attacked them with a hard object and a knife. No motive was given for the assault.
Police detained an unidentified suspect who denied the charges.
