Col Kittisak Sommat of the Patong Police said officers were called to the scene, on Nanai Rd, at around 8:30am.
Police together with Kusoldharm rescue workers arrived to find the body the woman hanged by a rope to the awning.
Officers found no marks on the woman’s body to indicate she had been involved in an altercation, Col Kittisak said.
There was no evidence of fighting or ransacking in the room, he added.
However, he added that the woman’s body was taken to Patong Hospital for further examination.
The woman’s mother told police by phone that her daughter worked in a massage shop on Phra Baramee Rd in Patong. She also said her daughter was prone to periods of instability.
“The mother was on Samui yesterday and called her daughter in the morning, but her daughter did not answer her calls,” said Col Kittisak.
“The mother called to the shop, and a staffer told her that her daughter was working.”
“The woman left the shop around 11am. After that nobody could contact her.” he added.
“Police are questioning witnesses and checking CCTV footage from the nearby building,” Col Kittisak said.
