Two men have been arrested over the murder of underworld figure Mejid Hamzy, who was gunned down outside his southwestern Sydney home last year.
Hamzy was ambushed early in the morning in front of his Condell Park home last October and died at the scene.
The two gunmen lay outside the 44-year-old's home, waiting for him to emerge.
Hamzy is the brother of jailed Brothers 4 Life gang leader Bassam Hamzy.
Police raided six properties across Greater Sydney on Wednesday morning and arrested two men.
A 38-year-old was arrested at a Liverpool home and is expected to be charged over the murder.
A 44-year-old man arrested in Croydon is expected to be charged in relation to the concealment of a car used in the crime.
Police investigating Hamzy's murder believe the incident is linked to a gang war between the underworld Alameddine and Hamzy families.
A friend of the Alameddine family was assaulted just days before the murder.
Last week police released CCTV footage of cars they believed were used in the murder.
Last month, Hamzy's cousin - Bilal Hamze - was ambushed and executed by gunmen in the heart of Sydney's CBD, in what police feared was an escalation of violence between the families.
