Police say they are on high alert for revenge attacks after a bikie was shot dead in a “cowardly and brazen” ambush outside his home in Sydney’s south-west.

Fares Abounader, a former ally of slain former Comanchero boss bikie Mick Hawi, was killed in a targeted drive-by shooting at his home in Wall Avenue, Panania, about midnight last night.

Police said Mr Abounader’s family, including his wife and young child, were home when he was shot multiple times after returning from a night out.

Family members, a neighbour and paramedics performed CPR, however he died at the scene.

Police are investigating whether Mr Abounader’s recent defection from the Comanchero outlaw motorcycle gang (OMCG) to the Bandidos could be behind the attack.

Detective Superintendent Rob Critchlow said police were being “very open minded” despite it being “very easy to jump to conclusions due to who this fellow is and who he used to spend time with”.

“The use of firearms to prosecute internal politics for any group in a public place is totally unacceptable and it cannot stand,” he said.

Detective Superintendent Critchlow described the shooting as “very calculated, very deliberate and quite brazen”.

“Despite the fact that the victim was known to police it doesn’t change the fact that he was a family man.

“Regardless of how he’s made some life choices, no-one deserves to be treated like this, murdered in such a callous fashion at the front of their home.”

Detective Superintendent Critchlow said police had deployed specialist teams to prevent further OMCG violence.

“Often these crimes result in tit-for-tat behaviours and we stress upon anyone who is considering doing that to refrain because it will only make the situation worse.”

Police are searching for a late-model, white SUV or wagon last seen travelling east from the crime scene in Wall Avenue.

Mr Abounader was charged over his involvement in the 2009 airport brawl between rival bikies in which Hells Angel member Anthony Zervas was bludgeoned to death with a bollard and repeatedly stabbed.

Mick Hawi, who served time for manslaughter over the incident, was shot dead in 2018 outside a Rockdale gym. Two men are currently facing trial for his alleged murder.
