The woman, whose name was withheld, had been working for some years as the maid and caretaker of the unoccupied house in Soi Phaholyothin 2 for a former advisor at the Defence Ministry, General Wichai Hongsakul.
Wichai's son-in-law Wisal Cherd-areekit, 42, who went to the house on Thursday night and discovered the body, told police he had two weeks earlier advised the maid to go and see a doctor as she was obviously sick.
Police initially suspected she might have died from an illness because there was no evidence of a struggle, no signs the room had been ransacked and no valuables were missing.
They have not ruled out rape, however, as the woman was found naked, Chayut said.
The results of tests carried out on the woman are likely to be known next week.
