A 37-year-old Myanmar woman was arrested earlier this month at a home in Samut Songkhram on charges of human trafficking and providing shelter to illegal migrants in an extended probe into a human trafficking ring, police said.
The arrest was announced on Friday at a press conference by the Immigration Bureau.
The suspect, who was identified only as "Ms A", was implicated by a Thai suspect, Thanachai Mangthim, a mail van driver who had been caught transporting 13 illegal Myanmar migrant workers to the Thai-Malaysian border in Songkhla in May.
Mr Thanachai told police that he had been contacted by a Myanmar woman several times to transport migrant workers. He identified "Ms A" as his contact in photos shown at the Samut Songkhram immigration office.
The Songkhla provincial court approved the arrest warrant on June 17 and a combined task force tracked "Ms A" down to a house in Samut Songkhram where the arrest was made on July 4. Police also seized a bank account that showed around four million baht in annual cash flow in connection with the case.
