A man has been arrested over the execution-style killing of bikie teenager Bassil Hijazi last year.
The 18-year-old from Hurstville was approached by two men and shot dead while sitting in his car at the back of a gym at 9.40pm on July 29.
He got out of the vehicle and ran a short distance before collapsing on the ground.
Mr Hijazi, who had links to the Comanchero bikie gang's controversial South Chapter, had survived an attempt on his life a fortnight earlier when his car was sprayed with more than a dozen bullets at Bexley.
He escaped then with a minor wound to his neck.
At 6.30am on Wednesday, police arrested a 23 year-old man at a home in Five Dock. He was taken to Burwood police station where he is expected to be charged with murder and possession of a prohibited firearm.
In December, police released CCTV images of the man wearing a white hoodie and walking near the scene of the shooting with his hands in his pockets.
On Wednesday, police released fresh CCTV footage of another man believed to have also been involved in Mr Hijazi's death.
The man in the footage was wearing a long-sleeved hooded top, with a zip at the front.
The CCTV recording was taken from a property near the Bexley car park where Mr Hijazi was shot dead.
Police have also released CCTV of a white Toyota Corolla sedan, possibly a 2011 model, which was in the Bexley area at the time of the shooting.
Mr Hijazi's death came during a period of heightened tensions within the Comanchero.
Weeks before his death, members from three other Comanchero chapters - the East, Wild West and Milperra - raided the Turrella clubhouse of the South Chapter.
Wearing all black and armed with guns and torches, the bikies stormed the clubhouse and told the 20 South members meeting inside that their chapter was to be closed down.
The South members were then told they could defect to one of the other chapters or "hand back your colours".
