Police with dogs have searched bushland on a property in rural NSW as part of the investigation into the abduction of Sydney grandfather Chris Baghsarian.

Police swarmed the property at Glenorie, on Sydney’s north-west fringe, late on Sunday and were expected to continue the search on Monday morning.

The property is about 15 kilometres from an abandoned house at Dural that police last week identified as a possible kidnappers’ hideout.

Police also issued an appeal for public information about two suspicious vehicle fires on Good Street, Westmead, 15 kilometres from the kidnap scene, about 11.30pm on Tuesday.

Police said the two vehicles were partially destroyed.

Detectives believe the targeted vehicle was a 2022 Toyota Corolla with the Victorian registration 1UZ2BU. It was reported stolen from a Victorian address a month before Mr Baghsarian disappeared.

Officers searched a derelict property in the semi-rural suburb of Dural on Sydney’s north-west outskirts on Thursday night after identifying it as a makeshift stronghold for the kidnappers.

Investigators believe the Corolla is linked to the crime scene at Dural.

The mysterious case has stumped police, who, in the absence of a ransom demand, have used media to directly appeal to the kidnappers to return the grandfather to a safe location.

Officers are unclear how long the grandfather spent at the Dural property.

Hopes are fading that investigators will find Baghsarian alive more than a week after he was taken captive from his north-west Sydney home.

Baghsarian was reported kidnapped from the North Ryde property early on February 13 when three men stormed the property and bundled him into an SUV.

Baghsarian’s family spoke publicly for the first time earlier in the week, describing the kidnapping as a surreal and harrowing ordeal.

“Our family is living through a nightmare we never thought possible,” they said.

Anyone who may have seen or heard anything, or has CCTV, dashcam and or mobile footage relating to the kidnapping, or witnessed any sort of suspicious activity in the Westmead area since last Friday is urged to contact detectives.
