Two men have been arrested in relation to the alleged kidnapping and murder of Sydney grandfather Chris Baghsarian.

Baghsarian, 85, who disappeared from his North Ryde home shortly before 5am on Friday, February 13, was believed to be the victim of a mistaken-identity abduction.

Suspected human remains police believe are Baghsarian’s were found in grassland near a golf course in the semi-rural Sydney suburb of Pitt Town yesterday morning.

At about 6.30am today, police executed two search warrants in Kenthurst and Castle Hill.

A 29-year-old man was arrested at the Kenthurst address, and a 24-year-old at the Castle Hill address.

They remain in police custody, but no charges have been laid.

“We welcome the news of the recent arrests in relation to the kidnapping of our father and grandfather,” Baghsarian’s family said in a statement distributed by police.

“As we continue attempting to come to terms with this incident, we ask that media respect our privacy.”

The family said they would not be conducting interviews.

Officers continue to comb the crime scene where Baghsarian’s suspected remains were found this morning.

NSW Premier Chris Minns said yesterday the discovery of Baghsarian’s remains was “an incredibly tragic development”.

Police said a car forensically linked to the 85-year-old was seen a day after his kidnapping near where his suspected remains were found this morning.

“While formal identification is still underway, this is an incredibly tragic development, and our thoughts are with the friends and family of Mr Baghsarian at this heartbreaking time,” Minns said.

“This kind of brutality has no place in our community. Police will not stop until they capture those responsible and bring them before the courts. The full weight of the law must come down on these people.”

The human remains were discovered near a golf club in Pitt Town in the city’s north-west about 8am yesterday during the search for the 85-year-old.

Police are awaiting testing to positively identify the remains as Baghsarian.

A grey Toyota Corolla forensically linked to an abandoned stronghold in Dural was spotted in Pitt Town about 9pm on February 14, police said.

Police believe those who kidnapped Baghsarian may have taken the grandfather to the property after the abduction.

During a raid, officers seized evidence, including disturbing images of the missing grandfather with his alleged kidnappers.

Videos of Baghsarian have also been sent to police.

The car, which had cloned plates but is believed to have been stolen from Victoria, was found burnt out on Good Street in Westmead on February 16.

It had cloned plates of DVT007, and the Victorian registration 1UZ2BU.

Detective Acting Superintendent Andrew Mark said information regarding the investigation led police to the golf course.

“We’ve traced that vehicle that we suspect was involved and that can forensically link the vehicle to Mr Baghsarian, and to the stronghold that we have spoken about in Dural,” Marks said.

“Putting that together is why we believe it’s Mr Baghsarian.”

An autopsy will be conducted.

Baghsarian’s family are “deeply upset” by the discovery and have asked for privacy.

Police will now focus efforts on identifying the offenders.

“The efforts that have gone in, and the response that has come from the public, we’re all outraged that this has happened to an innocent man,” Marks said.

“I am proud of the police and the efforts. Police have been working 24 hours a day since Friday the 13th.”

Marks said he is confident investigators will use every resource available to bring the perpetrators to justice.

The search for Baghsarian

9News understands the remains were wrapped up in what appeared to be a carpet or towel.

Police searched dense bushland near Glenorie, about 15 minutes further east, earlier in the week.

Shortly before 9am yesterday, a number of police vehicles left that search base to travel to a patch of overgrown grassland near Pitt Town Bottoms Road.

Once they arrived at the location, a blue tent – signifying the location of the remains – was raised in minutes.

The overgrown piece of land is located in semi-rural surroundings, with businesses including turf farms nearby.

Police on the scene this morning included tactical, general duties, and forensics officers as well as investigators.

The area has been carefully combed, with officers conducting line searches around where the remains were found.
