Four men from Sydney's west are expected to be charged on Thursday with the murder of Brendan Vollmost, 23, who disappeared after CCTV footage showed him being chased into his yard and then abducted by a group of men.
Detectives and Riot Squad officers arrested three of the men - aged 33, 25 and 25 - in homes at Lalor Park and Quakers Hill about 6am on Thursday.
A fourth man, aged 25, was arrested when a car was stopped in the Hawkesbury area. The men are thought to be linked to the Blood Brothers gang.
The chilling CCTV footage may have captured the final, desperate moments of Mr Vollmost's life.
The footage shows the 23-year-old and two friends in a car, pulling into his driveway at Cox Street, South Windsor, at about 10.30pm on March 31.
The car is still moving when Mr Vollmost opens the door and jumps out. He and the driver run from the car, leaving the third person inside the vehicle. He frantically tries to scramble over the fence before it swings open and he and the driver run into the yard.
At almost the same time, a white Hyundai i30 arrives. Several men jump out of the car and race up the driveway, pursuing Mr Vollmost into the yard.
Police believe Mr Vollmost was bashed to death in his back shed while his girlfriend was inside the house they shared, and that the men carried Mr Vollmost out of the yard, bundled him into their car and drove away.
Previous reports suggested the crime may be connected to drugs and Mr Vollmost might have been involved in a collision with the Hyundai just before he was abducted.
Detectives are still searching for Mr Vollmost's body and the Hyundai, but suspect the car is still in the western suburbs because it hasn't been detected crossing any of the toll points on the major highways out of the Hawkesbury.
