A baby boy who was allegedly assaulted by his teenage father in a Bunbury hospital room has died.
The 27-day-old boy was supposed to be getting out of hospital for the first time since his premature birth when he was allegedly attacked.
He has been on life support in Princess Margaret Hospital with critical head injuries after he was found injured on February 15.
Police have charged the baby’s 15-year-old father with aggravated grievous bodily harm.
It is believed that the boy’s 16-year-old mother returned to the room after briefly leaving to get some food and found the baby unresponsive and the father claiming to be trying to give him CPR.
It is unclear exactly how he was injured but homicide detectives and forensic officers spent time at Bunbury Hospital, where the baby had been cared for since his birth last month.
It is understood his Perth-based mother had returned to her home town of Bunbury for her son’s birth in order to have the support of her immediate family.
The baby had been taken into the care of the Department for Child Protection, leaving chief executive Terry Murphy to make all medical decisions.
"I can confirm the baby boy injured in Bunbury last weekend has passed away with his family at his bedside,” Mr Murphy said.
“No decision was required to be made regarding life support systems.
"I would like to express my sadness at this tragic loss, and offer my sincerest condolences to all members of the family. "
Child Protection Minister Helen Morton had asked for an investigation into the “distressing and tragic incident”.
