A man, 31, has been charged with firearm possession after he was allegedly forensically linked to a handgun found in a garage used to store a getaway car used in the murder of Mahmoud "Mick" Hawi.
Hawi, 37, was shot by a man as he got into his car outside a gym on West Botany Street, Rockdale just after midday on Thursday, February 15.
He was taken to St George Hospital, where he later died.
The alleged shooter ran from the scene before being driven away by another man in a Mercedes-Benz station wagon, which was later located on fire near Chandler Street, Rockdale.
Both men were seen running from the burning vehicle and are alleged to have fled to the Bexley area in a second vehicle – a Toyota Aurion – which was later recovered in March at Beaconsfield.
Detectives from the State Crime Command’s Criminal Groups Squad are continuing to investigate the circumstances surrounding the shooting under Strike Force Amirs.
A police spokesman said, as part of the investigation, detectives located a firearm during a crime scene warrant at a home at Bexley.
"The firearm was seized and underwent forensic and ballistic examination," he said.
"Following further inquiries, a 31-year-old man was arrested at Campsie Police Station about 7.30pm yesterday (Wednesday).
"The Belmore man was charged with possess prohibited pistol and refused bail to appear at Burwood Local Court later today (Thursday 28 February 2019)."
