Police are investigating after a 31-year-old woman was found dead in her rented cubicle in an old tenement in Sham Shui Po yesterday. Neighbours had reported a foul smell coming from the room in the Ki Lung Street building. The flat was condoned off for two hours as officers collected evidence. An investigation found no wounds on her body and nothing suspicious. A police source said the woman was a drug addict and might have taken an overdose.
