Officers were called to the scene at about 7:30am.
The victim, identified as Ritthakiat Petchploy, registered as living at the home, was discovered lying shirtless on a bed with an electric wire wrapped around his neck.
According to investigators, there were no signs of a struggle or forced entry at the scene.
Authorities were alerted to the incident by the victim’s mother, Saithip Samnam. She reported that she had left the house around 6am to buy breakfast for her son and returned about an hour and a half later.
Unable to enter the bedroom, Ms Saithip peered through the window and found her son unresponsive.
The police were called immediately, and an investigation team, including forensic experts from Vachira Phuket Hospital, conducted an initial examination of the body.
Ms Saithip told police that her son had a history of mental health struggles and had attempted suicide on two prior occasions.
Family members expressed no suspicions regarding the cause of death, which police are treating as a suicide based on the evidence collected.
