UPDATE: The general manager of a daycare centre in Helena Valley where a child was found dead in a father's car has praised workers for attempting to resuscitate the child.
The 11-month-old boy was found in the back seat of a dark-grey Honda Civic being driven by the baby's father about 4pm yesterday at the Ladybugs early learning and care centre on Torquata Boulevard.
Staff at the centre performed CPR on the boy but their efforts to resuscitate him were unsuccessful.
Ladybugs general manager Kim Beange said she was proud of her staff's efforts to help the boy while ensuring other children were not affected.
"Our staff’s professionalism came to the fore and they remained vigilant throughout this time, and at no point were other children in attendance aware of the circumstances occurring," she said.
Ms Beange said all staff had been offered professional counselling and support services and all workers had returned to work today despite the tragic circumstances.
"Our thoughts and condolences are with the parents of the child and their family through this tragic time," she said.
Police are not treating the baby's death as a homicide, but inquiries into the circumstances leading up to the boy's death are continuing.
It is understood the boy’s father arrived at the day care centre about 4pm to pick up his son, but staff at the centre informed him the boy had not been dropped off there that morning.
He returned to his car and found his unresponsive baby inside.
Police were speaking to the boy’s parents last night and they did not know how long the boy had been in the car.
Temperatures in Perth peaked at 26C on Wednesday, the warmest day in Perth for months.
A spokesman said officers were treating the tragedy as a sudden death and not a suspected homicide.
The results of a post-mortem examination will be reviewed as part of the investigation.
A report is being prepared for the Coroner.
