The younger brother of slain Sydney standover figure Walid Ahmad says he's still being threatened in jail after the fatal shooting of Safwan Charbaji four years ago.
Mahmoud "Brownie" Ahmad, 37, fled overseas after 32-year-old Charbaji was shot outside a smash repair business in Condell Park, in the city's southwest, in April 2016.
His death inflamed tensions between warring factions of Sydney's underworld that simmered for more than a year.
Ahmad travelled to Lebanon soon after the bloody clash but was arrested when he returned to Australia in March 2017 before pleading guilty to manslaughter over Charbaji's death.
In documents tendered at his sentence hearing in Sydney's Supreme Court on Friday, Ahmad admits to firing a "warning shot" as he attempted to leave the gunfight.
Although Ahmad had no intention of involving himself in a dispute when he arrived outside the A-Team Bodyworks shop, a melee broke out between two groups.
Charbaji handed a pistol to underworld figure friend Fawaz Elmir before exchanging fire with Ahmad's brother, who was in possession of a Glock pistol.
The gun battle - which Ahmad took no part in - appeared to come to an end when Ahmad group member Abdullah El Masri was shot in the jaw.
Picking up the wounded man's revolver, Ahmad walked briskly towards his car to leave.
Elmir, who by this time was inside a silver Camry, pointed his pistol out the driver's side window in his general direction.
Ahmad purposefully discharged a "warning shot" above the car as his brother fired through the front window, hitting Charbaji in the head and chest while he sat in the passenger seat.
"Walid did so believing this was necessary in self-defence," the agreed facts state.
"Objectively, it was not."
Defence barrister David Dalton SC said on Friday that Ahmad fled to Lebanon for 11 months after the shooting because he "feared for his life".
Later that month, his brother was gunned down at a Bankstown shopping centre.
During his psychological evaluation in early July this year, Ahmad apologised to Charbaji's family and said he regretted everything.
The father of four said his wife was "made to fear for her life" after he'd already received death threats.
"He said threats against him have continued in prison," the psychologist wrote.
"He stated his regrets about the plight of Mr El Masri who was shot in the jaw during the incident, his brother's loss of life in the aftermath, and the large number of people affected including his own family."
Letters of support from Ahmad's family, friends and acquaintances were submitted on Friday for the consideration of Justice Richard Button.
He is due to be sentenced on September 3.
