Muang Mae Hong Son police investigator Lt-Colonel Worathan Kruachanta went to the provincial court at 10.30am on Monday to apply for the arrest warrant after an attempt to get warrants for three of the officers on Sunday failed.

The latest application was overseen by Muang Mae Hong Son superintendent Colonel Satasak Pimontip.

A police source revealed two women accused of procuring girls aged under 18 into forced prostitution had been interrogated and were sent to Bangkok on Sunday to face legal action by the Anti-Human Trafficking Division (AHTD).

The AHTD said if the women implicated state official in the scandal, arrest warrants would be issued as per the instruction of deputy national police commissioner General Srivara Ransibrahmanakul.
