Police were called to a Banna Avenue, Griffith car park following reports two children had been left unattended in a car with the engine running at about 1pm on Saturday.

They were aged two and nine years old.

Officers were also called to almost identical case that afternoon and responded to a supermarket car park at 3.25pm.

Again two children, aged four and 11, were left alone. The car was turned off, with all the windows up.

Police attended and spoke to the parents and are continuing their investigations, while both incidents have been reported to Family and Community Services.

The temperature in Griffith on Saturday peaked at 30.7 degrees.

Murrumbidgee Police District Inspector Kim Traynor said the four children were fortunate to have not been harmed.

"By leaving your child in a car you are placing them at great risk of dehydration and heat stroke, or even abduction," Inspector Traynor said.

"We are urging the community to be mindful, particularly as the weather heats up.

"Leaving your children alone in a car so you can grab a few things from the shops is not only dangerous, it is irresponsible."
