Boonyarit, an official in Mae Sa Riang, was transferred on Wednesday after he pushed for a transparent investigation of former governor Suebsak Iamwichan, who has been linked to a forced-prostitution ring in the province.

The home invasion took place at 3am at the house of Tai Punnanuphutthipong, 51, who had issued a statement calling for a probe of people who had pushed for Boonyarit’s transfer order, which was justified as being for Boonyarit’s own safety.
