Police in Perth say the death of a baby boy found inside a car parked near a childcare centre was a tragic mistake.
The boy, believed to be 11 months old, was found inside the back of his father's car outside the centre in the eastern suburb of Helena Valley on Wednesday afternoon.
The father arrived at the centre to pick up his son, but was told by staff he had not dropped him off that morning.
The boy was then found still strapped inside a capsule in the car.
The incident happened on Perth's hottest day in the past month.
