Father of young twins shot five times in failed underworld hit

A masked man sent bullets flying toward a newly-married father of newborn twins during a failed assassination attempt in Sydney.

Hayan Chandab, who reportedly associated with the Bandidos and Comanchero bikie gangs, spent two months in hospital recovering from the attempt on his life in July 2013.

Footage released by NSW Police on Tuesday shows a balaclava-clad gunman shoot Chandab five times outside his St Mary's home, in what his sister described as his past catching up with him.

Chandab, then 31, screamed for his neighbour's assistance as he was peppered with bullets - one grazing his skull while others lodged in his back, shoulder, abdomen and leg.

But the shower of shrapnel was not the end of the vicious assault.

After unloading his weapon, the gunman booted his victim in the face as he tried to protect himself, breaking his nose.

His sister Taghred, a former reporter, broke the "code of silence" to speak about how her brother survived the failed hit in the hopes of deterring "another generation of Australian boys of Middle Eastern origin" being lured into local gangs.

Pushing through the pain, Chandab was able to phone an ambulance. The father-of-two later told her he was "not ready to die".

"Lying in a pool of blood, he reached for his phone. There was so much he had to live for - he had just married and had seven-month-old twin boys," she wrote in the Daily Telegraph.

Ms Chandab claimed a wrongful imprisonment caused her brother to "spiral out of control".

"He got into street brawls and club fights. For my family, the real blow came when he walked through Mum and Dad's door wearing the colours of the Bandidos."

Police believe the former bikie's attacker is still on the streets and have renewed an appeal for information on the brazen attempt on his life. 

"I am sure there are people who know more about this incident than what has been passed on to the police already," Detective Inspector Brad Element told Ten News.
