Violent Attack at Chiang Mai Rice Research Center Following Bidding Dispute

On August 25, 2026, a violent incident occurred at the Chiang Mai Rice Research Center in San Pa Tong District, Chiang Mai, according to a report by Khaosod Online. Two representatives from a private company, identified as Mr. A and Mr. B, were attending a rice auction when they were approached by five men. These individuals allegedly pressured the victims to engage in price-fixing, a practice known locally as 'bid rigging.'

After the victims refused to comply and insisted on fair competition, the group of men reportedly attacked them using iron bars, batons, and knives. Mr. A sustained a knife wound to his right arm and was transported to San Pa Tong Hospital, while Mr. B suffered injuries to his head and face, requiring a brain scan. The victims have since filed a formal police complaint.

For residents and visitors, this incident highlights concerns regarding transparency and security at public research facilities. Notably, relatives of the victims have raised questions regarding the facility's security, as the CCTV system was reportedly non-functional at the time of the assault. Authorities have yet to confirm the identities of the attackers or provide further details on the investigation. As the situation remains under police review, those involved in local business or public tenders are advised to remain cautious.
