Detectives have arrested another two young men over the alleged botched kidnapping and murder of 85-year-old Chris Baghsarian.
Police arrested the men, aged 19 and 20 years-old, at properties in Western Sydney on Tuesday morning.
It follows the earlier arrests of another four people in relation to the grandfather's death, which police believe was a case of mistaken identity.
Mr Baghsarian was allegedly taken from his North Ryde home in the early hours of February 13, sparking a major search effort during which police urged his kidnappers to release him.
His body was found 11 days later near a golf club in the semi-rural suburb of Pitt Town in Sydney's north-west.
Police allege Mr Baghsarian was not the intended target of the kidnap-ransom plot.
