A search is continuing for a man who choked a woman with a cable bike lock in the yard of a Sydney unit block.
The 27-year-old woman was followed at the Ashfield property on Wednesday night before a man wrapped the cable around her neck and pushed her to the ground.
A man and woman who were sitting in a parked car heard screams and intervened before the semi-conscious victim was taken to the Royal Prince Alfred Hospital.
Acting Superintendent Andrew Graham on Thursday said the “frightening” attack was believed to be random.
Police have called for more witnesses and anyone with CCTV to come forward.
