Police are investigating whether a toddler died after accidentally being left in a hot car at a home in Sydney's west.
Emergency services were called to the home in Chester Hill on Sunday afternoon to reports a 22-month-old boy had been found unresponsive.
Paramedics were unable to revive him and he was pronounced dead at the scene.
Police were told the child was found inside a car at the front of the residence by family members when he could not be found inside the home.
The Daily Telegraph reports the boy was left in the car for several hours, with temperatures reaching 34C.
The boy, said to be a twin and the youngest of six children, was reportedly left in the care of someone else while his mother was out.
His grandmother, who lives at the house, was taken to hospital suffering from shock, the paper reports.
Police have established a crime scene and a report will be prepared for the coroner.
