Two men have been arrested over the execution-style murder of Sydney underworld figure Mejid Hamzy, who was gunned down two years ago.
The brother of Bassam Hamzy - the head of the Brothers 4 Life gang - was shot dead outside his Condell Park home in Sydney's southwest on October 19, 2020.
The 44-year-old was found critically wounded by emergency services and died at the scene.
NSW Police believed the murder was part of the long-running turf war between the feuding Hamzy and Alameddine families.
Detectives from the State Crime Command's Criminal Groups Squad and the NSW Crime Commission and South West Metropolitan Region established Strike Force Courier to investigate the killing.
Officers attached to Raptor Squad also helped with the investigation.
Since then, strike force detectives have charged two men - aged 38 and 44 - who remain before the courts.
Officers from the Tactical Operations Unit and South West Metropolitan Operations Support Group carried out raids at homes in East Hills, Panania, Bankstown and Padstow just before dawn on Thursday.
Police vision of the high-visibility operation showed three separate arrests at East Hills, Panania and East Hills.
All three men were taken to Bankstown Police Station.
The vision also showed police seized a large amount of cash during the arrests.
Two men are expected to be charged with murder over the 2020 killing.
Police will hold a press conference later on Thursday.
