The inspection was led by Kosol Khamsiri, director of the division for investigation into alleged corruption by state agencies. Kosol said he conducted the inspection following a complaint filed by Democrat Party MP Watchara Phetthong.
Kosol said he would seek more documents from House of Representatives secretary-general Suwichak Nakwatcharachai on the renovation project and may also summon certain officials to testify if needed.
After he had received enough information, he would make a decision by early next year on whether to proceed with the inquiry.
