Two more men have been charged with murder as part of an investigation into the alleged kidnap and murder of Sydney grandfather Chris Baghsarian.

Mr Baghsarian, 85, was kidnapped from his North Ryde home in the early hours of February 13, in what police have described as a case of mistaken identity.

His remains were located 11 days later near a golf club in Pitt Town.

Four people have previously been charged and remain before the courts. 

Following extensive inquiries, NSW Police conducted a number of raids on Tuesday morning with 19-year-old Brendan Gorman arrested at a Shalvey property, and 21-year-old Codi Fuller at a Silverwater address.

They have been charged with murder and take/detain in company with intent to ransom occasioning actual bodily harm. 

Detective Acting Superintendent Stuart Gordon said police believe the two men were ‘directly involved’ in Mr Baghsarian’s detainment at a Dural property.

‘It was during this time that we allege Mr Baghsarian died. We further allege these two males were involved in the disposal of his body that was later discovered on the 24th February,’ he told reporters on Wednesday afternoon.

‘We believe there are a number of other persons involved in various ways in the disappearance of Mr Baghsarian and his ultimate murder. Our investigations will not stop until each and every one of them has been apprehended.’ 

19-year-old Gorman was also charged with failing to comply with a digital evidence access order direction.

They were refused bail and their matters were briefly heard at Mt Druitt Local Court on Wednesday.

Their cases were adjourned to July 17. 

Supt Gordon said police have noticed an uptick in young males ‘who are committing the most serious of criminal offences, often for people they don’t know…and little money.’

The arrests come nearly two months after a fourth man – 19-year-old Moustafa Ohrok – was charged over Mr Baghsarian’s alleged kidnapping and murder.

Gerard Andrews, 29, and Daniel Stevens, 24, and Deklin James Donnelly, 23, have also been charged with murder. They remain in custody.

Court documents detail allegations that Andrews and Stevens transported Mr Baghsarian to a semi-rural makeshift stronghold in Dural, on the city’s outskirts. 

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

Mr Baghsarian’s family previously described the ordeal as a nightmare.

They have 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’.
