Two armed home invasions in two days in Perth’s northern suburbs have left three people shaken.

A young couple in Ballajura was threatened with a handgun and crowbars when three masked men forced their way into a home on Desault Cove on Friday.

The intruders escaped in a dark coloured, Volkswagen Golf GTI.

Neighbour Wendy Harris said, “there were three masked men that came in and threatened them with industrial crowbars.”

“They climbed over the gate and got the car port door open then broke the door down and attacked them.”

A home on Redfern Street in North Perth was targeted on Thursday in an unrelated armed robbery.

Intruders armed with a gun threatened the man who lived at the house at 6.30am.

They were reportedly wearing masks and dark clothing and left in a BMW, which is believed to be stolen.

Police are hoping members of the public can help solve both these crimes and anyone with information is asked to phone Crime Stoppers on 1800 333 000.
