Police are investigating reports of a home invasion in Yokine yesterday afternoon when three people were assaulted and robbed.

The report said a man in his 30s returned to his home about 4.00pm to find two men inside the house.

The men allegedly assaulted the man with blunt weapons before binding his hands behind his back while demanding money and property.

The man’s parents — aged in their 50s — arrived about half an hour later and were also assaulted.

Police said the two offenders were joined by a third man before all three fled with cash and goods.

The victims were taken to Royal Perth Hospital by ambulance with head and body injuries including lacerations, bruising and swelling.

Police are asking for anyone with information to contact Crime Stoppers on 1800 333 000 or to make a report online.
