At 1am, Lt Col Suthichai Teinpo and Narcotics police went undercover and operated a sting where they found four people selling drugs to both locals and tourists and pretended to be working as a disguise.
The offenders were calling out both locals and tourists to see if they needed a taxi, but they were actually selling drugs.
Police arrested Umawadee Wijitsopa, 34, with one bag of ya ice (0.8 gram), Jaknarin Sanyakit, 25, with two bags of ya ice (0.40 gram), Nateethon Kitjarad, 27, with three bags of ya ice (0.3 gram), and Somsak Onoothon, 36, also with three bags of ya ice (2.1 gram).
Police took them to Kathu police station where they were later charged with possession of a Category 1 drug with intent to sell.
