Mr Ayoub, also 22, was found with gunshot wounds and slumped under a tree in a Punchbowl park on a Monday afternoon in late June. He died on the grass not far from a children's playground.

Fairfax Media reported in June that police believed a group of men were involved in the fatal shooting and that Mr Ayoub was deliberately targeted.

The day after the shooting more than two dozen heavily armed police raided a Wiley Park home.
