The couple were arrested at a road checkpoint jointly manned by troops and police on a highway in Lampang’s Mae Prik district late Sunday night.
The two were identified as Saisayam Jaimoi, 27, and his wife, Somruethai Bua-in, 27. Both are residents of Chiang Rai’s Phan district.
The drugs were found in a secret compartment built under the truck. They had their son sit beside them.
Authorities made the truck pass through an X-ray scanning machine at the checkpoint and found the drugs.
The couple said they were hired by a drug agent in Chiang Rai’s Mae Sai district to deliver the drugs to a buyer in Bangkok.
