NAKHON SAWAN - Four men were arrested with 1 million speed pills while travelling from the northern province of Chiang Rai to the Talad Thai farmers' market in Pathumi Thani province, close to Bangkok.
Acting on an informant's tip, narcotics suppression police followed two pickup trucks registered in Chiang Mai province from a border area in Chiang Rai's Mae Fa Luang district.
They stopped one of them, a brown Toyota Vigo truck, on Phahon Yothin Highway in tambon Pak Nam Pho of Nakhon Sawan's Muang district early Thursday morning.
Police said they found about 1 million methamphetamine pills in 500 packs in the truck, and arrested its driver Settha Lee-anyamanee, 22, from Lamphun's Mae Tha district, and passenger Chaloemsak Thanomrungruang, 20, from Chiang Mai's Mae Rim district.
Police then stopped the other truck, a grey Toyota Vigo that had been leading the vehicle carrying drugs, on Phahon Yothin Highway in Phayuha Khiri district. Two men from Mae Rim - Surachai Thanomrungruang, 19, and Theeranai Preeyasakul, 20 - were arrested.
Mr Settha reportedly confessed that they were hired to transport the narcotics to the Talad Thai farmers' market in Khlong Luang district of Pathum Thani.
