Mr Assaad had also beaten a drive-by murder charge in 2010 relating to a love triangle. Crime figure Walid "Wally" Ahmad was shot dead at a Bankstown shopping centre on April 29. He was found not guilty of shooting Mohamad Alahmad, 37, six times as he sat in his BMW in the driveway of his South Granville home. Police had alleged that Mr Alahmad's ex-wife was in a relationship with crime boss Nasser Kalache however she had started talking to Mr Alahmad about a possible reconciliation. Police had alleged Mr Kalache ordered Mr Assaad and another man to kill Mr Alahmad. Mr Assaad was found not guilty in November 2010, two years after the shooting.

On Tuesday morning, police were looking for the black car, possible an Audi sedan, seen speeding away from the scene of the latest shooting. "Two people got out of that vehicle armed with firearms and shot a person who was well known to us," Detective Chief Inspector Grant Taylor, from the Homicide Squad, said on Tuesday afternoon. Police believe the two gunmen and getaway driver had watched their victim as he left home that morning. They observed Mr Assaad move one car out of his driveway and then ambushed him as he walked back up the driveway to get in another car. His mother was inside at the time and was "hysterical," Mr Taylor said.

Police have called for anyone who saw a black car loitering in the Georges Hall area or speeding away after the shooting to come forward. "The motivation behind this murder is not really known and it would be not the right thing to do for us to speculate exactly why he was killed," Mr Taylor said. An unnamed witness told 2GB that he heard up to ten gunshots coming from the house. "Then I ran out the front of this property and a car came speeding away from the scene," he said.

"My daughter said to me, 'mum gunshots' but I thought it was machinery," she said. "It sounded like a quick succession ... like an automatic." Her daughter said she heard six to seven gunshots. "I was about to go in mum's car and I heard boom boom boom," she said. "I was like, 'Mummy mummy shut everything please hide, shut the doors, shut the windows.' " Neighbours said the man moved into the home about six months ago with a wife and young children.
