CCTV has captured a violent robbery of a mother as she pushed her two children in a pram in Perth's eastern suburbs.
The footage shows a teenage girl dragging the woman by her hair while repeatedly hitting her over the head, knocking the pram over in the process.
Police allege the 37-year-old woman was walking with her children at about 12.40pm in Smallman Place in Ashfield on Monday when she was assaulted by the 15-year-old girl, who tried to steal her handbag.
