Police found the man after being called to Pendle Hill at 1.40am (AEST) on Sunday. He is being treated at Westmead Hospital and forensic experts are examining the scene. The incident is the latest in a string of stabbing attacks during the last week. It comes as a man is due to appear in court in Parramatta Bail Court on Sunday charged over the stabbing death of a 23-year-old pregnant woman in Maroubra. Allira Green was found by emergency services with a stab wound to her chest about 1.15am (AEST) on Saturday. The 23-year-old died at the Maroubra unit, in Sydney's south. A 38-year-old man has been charged with her murder. Police are also investigating the stabbing of 30-year-old woman, who survived and underwent surgery, in Westmead on Thursday and the fatal stabbing of a 28-year-old woman at Kyeemagh last Tuesday. Also on Thursday, a group of robbers stabbed a 42-year-old man in the stomach after he refused to hand over his bag in Sydney's west.
