Pol Snr Sgt-Major Rapong Phanompakdee, 45, was found hanging from a staircase in front of his bathroom at 11.30am. A medical examiner said he had been dead for at least four hours before the discovery.
An initial police inquiry found that Rapong, who was generally cheerful, had just bought construction materials to build a garage next to his house. They suspect that he committed suicide over a personal problem.
His body was sent for an autopsy and his relatives were notified of his death.
