A shooter is on the loose while a man is fighting for his life after he was found lying in a pool of blood from a gunshot wound outside a western Sydney primary school.
An off-duty nurse found the man, believed to be in his 30s, lying in a church driveway across the road from St John Vianney Primary School in Greenacre on Friday morning.
The nurse, who would only give his name as Sam, said he applied pressure to the victim's wounded knee.
Neighbours said they heard several gunshots around 9.20am and Sam said there were two bullet casings on the ground near the victim.
"He looked a little pale in the face ... of course anyone would be distressed if they got shot," Sam said of the victim.
A Liverpool Hospital spokeswoman said the man remains in a critical condition on Friday night.
The nearby school was locked down, with police placing a 100-metre cordon around Pandora Street.
The school lockdown was lifted just after 10.30am and parents collected their children.
"It is really worrying because it is the second time something like this has happened near the school," a mother told AAP.
The mother, who didn't want to named, said the school had kept parents well informed with several text messages.
"Things will happen everywhere in any suburb, but having said that, I believe the school have done what they could to protect the children and themselves," she said.
"I fear the security of our kids. I would love to see more security."
Her daughter said she was happy to be reunited with her parents.
"I felt scared because I didn't know what was happening and the first announcement that he (the principal) made was to lock the doors," the student said.
"So my heart started racing."
