Woman Faces Charges For Allegedly Leaving Kids In Car For An Hour

A woman is set to be charged after she allegedly left her two children inside a hot car while she went to the shops in Sydney's southwest.

Police allege the 36-year-old woman went shopping and left her boys, aged five and eight, inside the car at a Liverpool carpark about 12.45pm on Saturday.

About an hour later, people passing by discovered the children and contacted police, who found them to be dehydrated.

The woman was spoken to at the scene once she returned to the vehicle and will be issued with a future court attendance notice for leaving the children in a motor vehicle.

A court date is yet to be determined.

Police say the incident is a reminder of the dangers of leaving children and pets alone in cars.

"On a typical summer day, the temperature inside a car (even with the windows rolled down a little) can quickly rise above 50 to 60 degrees," police said.

Children are at great risk for heat stroke, which can lead to a high fever, dehydration, seizures, stroke and death.
