Colonel Woradej Dejraksa, commander of the Fifth Infantry Regiment based in Songkhla’s Sadao district, said the five were arrested after a patrol unit of his regiment had spotted three vehicles on the Sadao bypass road in the morning.
The soldiers stopped the vehicles – two pickups trucks and an SUV – and found the kratom leaves (Mitragyna speciosa) inside.
The five suspects were identified as Prasert Saenwongprasong, 41, Yutthachai Chanthaprapha, 33, Nirand Suwanchinda, 44, Pongchan Chamroenhongrassamee, 22, and a 17-year-old boy.
They said they had bought the drugs from a Malaysian man for Bt200 per kilo, and planned to resell them for Bt500 per kilo, Woradej added.
