Mandurah Detectives are investigating a serious robbery in Mandurah.
Just after 5.10pm on Friday, three men entered the victims unit on Ormsby Terrace and demanded property.
The victim, a woman in her 40’s, asked the men leave and ran to escape.
One of the men physically restrained her and during a short struggle struck her on the face.
Another man searched her belongings and pulled off the gold neck chains the victims were wearing.
The victim managed to break free, picked up a Digeridoo and swung it at the men.
They ran out of the unit and were seen getting into a white sedan, similar to a Holden Cruze.
Detectives would like to speak to anyone who may have witnessed the incident or may have captured the men leaving the unit in the white sedan on dash-cam.
