Two teenage girls have been set upon by a group of young female offenders in separate incidents in Mandurah and Halls Head.
The trio allegedly targeted a 14-year-old girl near the Mandurah Foreshore around 3.45pm on Sunday, November 17.
The incident continued in the Smart Street Mall between Mandurah Terrace and Tuckey Street before the victim sought help from a nearby family who were sitting inside a pub.
"The second incident occurred about 4pm, and occurred on the Estuary Bridge on the Halls Head side and continued to the skate park," a WA Police spokesperson said.
"Members of the public assisted a 16-year-old girl who was being harassed and assaulted."
Three juvenile girls have been charged with aggravated armed robbery and attempted armed robbery and are due to appear in court next month.
Detectives wish to speak to anyone who saw either of the above incidents, involving three female juvenile offenders, particularly anyone who assisted the victims.
Anyone with any information, or vision relating to these incidents is urged to contact Crime Stoppers on 1800 333 000 or via www.crimestopperswa.com.au.
