Two hospitalised in violent armed robbery, thugs still on the run near Rockingham Beach

Two men have been hospitalised in a vicious and unprovoked gang attack at a popular beach south of Perth with the thugs responsible still on the run.

Up to four men were involved in the violent armed robbery near Kwinana Horse Beach at about 1.45am on Saturday.

According to police, the gang broke into a Mitsubishi Express campervan parked off Rockingham Beach Road and attack the two victims inside with a large object.

The offenders stole personal belongings, including several bank cards before leaving the scene in a white vehicle - similar to that of a Ford Territory SUV.

One of the victims, a 46-year-old man, was sprayed in the face with an “unknown substance” and left with serious hand injuries, while a 31-year-old man had minor cuts and abrasions.

They were taken to Rockingham Hospital.

Detective First Class Constable Ben Williamson said the stolen bank cards had been used, but would not go into detail on where the purchases were made.

“After the incident, forensics attended and seized a number of items, but they are still undergoing forensic investigation,” he said.

He described the attack as “unprovoked”, and said both victims had been shaken by the incident.

“The evidences suggests... that it was an isolated incident (and) opportunistic, and for that reason, we don’t think there’s any danger to the public,” he claimed.

“Nobody likes stuff like that to happen to them, especially when they’re planning a holiday, however, as far as I know, their plans are to continue with their travels and enjoy the lovely state of Western Australia.”

One of the victims is believed to have been a tourist.

The campervan also sustained extensive damage, including several smashed windows.
