❓ Content reviewed: A Facebook user claimed she was reported for defamation by Capt. Thammanat Prompao.
✅ Fact-check result: True content
📝 Summary: On 1 Dec 2025, a Facebook user named Suphaphorn Phosri posted that she had received a summons from an investigator at Mueang Phayao Police Station in a case in which Capt. Thammanat Prompao, Deputy Prime Minister and Minister of Agriculture and Cooperatives, filed a complaint against her on charges of defamation by publication.
The summons image shared by the Facebook user indicates that it is the first summons issued by Mueang Phayao Police Station, Phayao Province, dated 20 Nov, in a criminal case between Capt. Thammanat, represented by his authorized representative, Mr. Atit Manassa, as the complainant, and the Facebook user Suphaphorn Phosri, or Ms. Suphaphorn Phosri, as the suspect, from posts described as “defamatory statements published on a public Facebook page, causing damage to the complainant’s reputation, contempt, or hatred.” The summons ordered the suspect to meet Pol. Capt. Suchart Wongprakai, the investigator in charge of the case at Mueang Phayao Police Station, on 4 Dec.
However, the summons misspelled the suspect’s name slightly at the end, and Ms. Suphaphorn also posted her bank account number to request financial support for travel expenses to meet the investigator. These factors led some people to question whether the summons was a genuine official document.
🔎 Cofact investigation: Mr. Atit Manassa, named in the summons as the authorized representative of Capt. Thammanat told Cofact by phone on 3 Dec that Capt. Thammanat had indeed authorized him to file a complaint against Ms. Suphaphorn after finding that she had posted messages that caused harm and created misunderstandings about Capt. Thammanat.
Mr. Atit said that he serves as a board member of the Thammanat Prompao Foundation and is authorized by Capt. Thammanat to file complaints against multiple individuals who have published defamatory content about him, though he did not know the exact number of people currently facing legal action.
Cofact contacted Mueang Phayao Police Station, where officials confirmed that Pol. Capt. Suchart Wongprakai is indeed an investigator stationed there, but declined to provide information regarding the summons in this case.
