Two men – one dressed in Gucci, the other wearing Adidas – are likely to face murder and kidnapping charges over the botched snatching of 85-year-old grandfather Chris Baghsarian.

The Sydney man’s body was found in Pitt Town, in Sydney’s north-west, on Tuesday morning, about 11 days after he was snatched from his bed by three men.

Early on Wednesday, strike force detectives executed two search warrants in Kenthurst and Castle Hill.

In Kenthurst, police arrested a 29-year-old man, while a 24-year-old man was arrested at the second address. Both were taken to Riverstone Police Station for questioning.

“We expect that they’ll be charged in connection with the kidnapping and murder of Mr Baghsarian,” Detective Acting Superintendent Andrew Marks said.

“We will allege in court that these men participated in a joint criminal enterprise with other persons to kidnap Mr Baghsarian and ultimately where he was held hostage, where he came to his death. And  … they’ll be charged with his murder.”

Vision of the arrest shows the younger man, shirtless and in knee-length Adidas shorts, being marched out to a police vehicle by two armed officers as detectives look on.

Another image shows the older man slumped in the back of a police car wearing designer clothing. His head is down and his stomach protrudes from his shirt.

Wednesday’s developments came 11 days after three men stormed Baghsarian’s home and bundled him into a car in the middle of the night. Their raid was captured on video.

“We’re looking for all those that are involved, and we suspect that there’s more than three,” Marks said.

Police had vowed to throw every resource available at finding those who mistakenly snatched the 85-year-old. The recklessness in taking the wrong man and targeting a family member angered authorities.

“We’re outraged at this happening and the recklessness of these people,” Marks said earlier.

Chris Baghsarian was snatched from his home in Sydney’s north-west.

Police believe the intended target for the abduction was a relative of underworld-linked Sydney businessman Dimitri Stepanyan, who lived on the same street as Baghsarian.

On Wednesday morning, flowers were laid at the front door and near the patio of the grandfather’s home. Baghsarian’s family, who described the harrowing ordeal as a “nightmare”, expressed relief the alleged offenders had been caught.

“We welcome the news of the recent arrests in relation to the kidnapping of our father and grandfather,” they said in a brief statement.

They asked for privacy, as they come to grips with the death of their devoted father, brother, uncle and grandfather “who would never hurt a fly”.

Police repeatedly told the kidnappers they had the wrong person and publicly urged them to release Baghsarian, who required daily medication.

Detectives found the remains near a golf club in Pitt Town, a semi-rural area on Sydney’s northern outskirts, after people reported seeing a vehicle linked to the investigation in the area a day after Baghsarian disappeared. Marks said on Wednesday they had been confirmed as those of Baghsarian.

An autopsy will determine how he died.

Marks said police believe the 85-year-old died at an abandoned house in nearby Dural that was linked to the kidnapping earlier this week.

NSW Premier Chris Minns described Baghsarian’s ordeal as “a shocking violent crime” and said there would be a swift response to those responsible.

“[They] will not get away with it,” he said.

Asked last week about organised criminal groups targeting rivals’ relatives, Detective Acting Superintendent Brad Abdy labelled it “ridiculously disgusting”.

He was speaking about an investigation into the shooting of former Canterbury and Wests Tigers winger Matt Utai outside his home in Greenacre, in south-west Sydney, as he was about to drive to work.

The 2004 NRL premiership star was caught in the crossfire of his son Iziah Utai’s alleged criminal associations and escalating gang conflict, detectives believe.

“Criminals throughout history have been known to retaliate against other rival gangs [but] this escalation into what appears to be targeting innocent members of particular families, it’s ridiculously disgusting offences they’re committing,” Abdy said.

“These are ordinarily innocent people now being targeted by violent criminal syndicates, and they have no association with the criminality of the people in their particular families.”

A man and a teenager have since been charged with shooting with intent to murder over the Matt Utai incident.
