Neighbours last night described the horrifying moment a woman pulled up at a Western Sydney home and screamed to its occupants: "Your son has killed my daughter."
In the back of the car was the woman's seriously injured 2-year-old daughter.The child was fighting for life last night after police sources said she suffered a "vicious assault" at the hands of a man some time before 3.30pm.
About 5pm yesterday police arrested a 22-year-old man in Fairfield in relation to the attack.
