The undocumented migrants comprised five males and seven females.
At 10pm on Friday, officers of Navy's Mekong Patrol Operation Command arrested Pranee (last name withheld), a local of Ubon Ratchathani’s Sri Muang Mai district, near a border checkpoint in Na Pho Klang subdistrict, in Khong Chiam district, which shares a border with Laos.
One of the migrants reportedly said that they had travelled from several cities in Laos’ Champasak province, and had paid an agency in Thailand Bt4,000 to Bt5,000 per person to transport them to Bangkok to find jobs.
The suspect and the migrants were taken to Khong Chiam Police Station for questioning.
