Marine police and jet ski drivers on Friday launched a search of a Chinese tourist who went missing while driving a jet ski in the sea off Koh Samui on Thursday.
Led by marine police, about 20 jet skis took part in the search for the Chinese tourist, Zhen Wen-tuk, who was reported to be heading toward Koh Som when heavy rainstorm struck.
The owner of the jet ski then sent its men to look for Zhen because he was supposed to return the vessel after 30 minutes. But he could not be located and a complaint was lodged with the police in the evening.
Search began Friday morning with 20 jet skis being deployed and lasted the whole day, but still there was no trace of Mr Zhen.
