Police manning the roadblock on the Petkasem highway in Ban Pla, Tambon Khao Chairai, stopped two cars for searches. They eventually uncovered the illicit drug hidden in specially-built compartments of the two cars.
The two drivers, identified as Songkran Omkorkun and Somchai Tachampa, were held in custody for interrogation. They two admitted that they were hired 150,000 baht to deliver the drug from Udon Thani to customers in Phatthalung province.
The two suspects also claimed that they had made about 10 drug deliveries in about one year.
