An innocent by-stander has been shot after hearing gunfire outside his home in Sydney's west.
The 22-year-old heard gunshots at around 9:45 last night outside his home on Greystanes road, at Greystanes.
He went out to investigate and was struck by a bullet to the leg.
The man was taken to Westmead hospital where he's in a stable condition.
Police are searching for three men seen leaving the area - they've also interviewed other residents as witnesses.
