Seripisut submitted a letter to Anutin accusing the Director-General of the Department of Lands and the police of delays in revoking land rights at Khao Kradong. He strongly criticized business groups for seizing State Railway land to build a racetrack and other private enterprises.
On 10 June 2026, Police General Seripisut Temiyavet arrived at the government's complaint center 1111, Office of the Prime Minister, to submit a letter to Prime Minister and Minister of Interior Anutin Charnvirakul. The letter was received by Somphat Nilpan, advisor to the Office of the Prime Minister, requesting urgent investigation into the conduct of the Director-General of the Department of Lands and police officials regarding the delayed revocation of land at Khao Kradong.
Seripisut revealed that he originally intended to meet the Prime Minister in person to hand over the letter but was unable to do so, thus submitting it through the complaint center instead. The submission included five pages of documents and photographic evidence. He confirmed that over 5,083 rai and 80 square wah of land at Khao Kradong are owned by the State Railway of Thailand (SRT) as affirmed by final court rulings. However, the land titles have not been formally revoked, and the area is currently being used for a sports stadium, racetrack, and private businesses, constituting a violation of the law.
"This case has final judgments from the Supreme Court, the Court of Appeals Region 3, and the Central Administrative Court. I therefore call on the Royal Thai Police Chief to expedite investigations and prosecute all involved parties, including Nawin Chidchob and all those encroaching on State Railway land," Seripisut said.
Regarding the political aspect, Seripisut responded to Supachai Jaisamut’s statement threatening legal action against accusers by questioning the basis of Supachai’s remarks. He reiterated that he is performing his role as an opposition member without fearing anyone. He also criticized certain political parties in the ruling coalition for pursuing power for personal gain, involving money in politics, and appointments that suggest favoritism.
Seripisut also referenced Pornpoj Penpas, against whom he has already filed a complaint with the National Anti-Corruption Commission (NACC) for misconduct. He warned that if government agencies remain inactive, he, as a former police chief, will not let influential figures escape accountability and will proceed with further legal complaints against both political figures and related agencies.
Reporters added that on the same day, groups including the Network of Thai Student Reformers (NSTR), the State Enterprise Labour Relations Confederation (SELRC), and the State Railway of Thailand Labour Union also submitted letters on this issue. They called on the government to resolve the Khao Kradong case transparently and fairly.
