A 51-year-old man was arrested on suspicion of murder yesterday after telling police he had found his wife hanging from a tree behind their wooden hut in Sai Kung. He told police he and his wife had earlier agreed on a suicide pact. A postmortem showed the woman, 46, had died of 'pressure to the neck as a result of hanging', a police spokesman said. A note found at the scene, which police officers believed was written by the woman, said she was 'unhappy with her life'. Police received a report about 7pm on Wednesday that a woman's body had been found hanging from a tree near her home in Shui Hau Village. Officers found the woman unconscious on the ground and she was later certified dead by ambulancemen. A police spokesman said: 'Initial inquiries revealed that the deceased and her husband attempted to commit suicide by taking pills and drinking alcohol in the hut.' The husband told police he later found his wife hanging from the tree and immediately cut her down. 'He called their 25-year-old daughter for assistance and the daughter made a report to police,' the spokesman said. The husband was arrested on suspicion of murder and taken to Tseung Kwan O Hospital for treatment, where his condition was described as stable. Police said he would be held overnight at the hospital, where he was being treated for consuming a quantity of pills and alcohol. Wong Tai Sin District Crime Squad officers scoured the hut for evidence.
