A man has been charged with murdering a three-month-old girl who sustained brain injuries in Perth's northern suburbs.
Police say the baby was hospitalised on Friday after an incident at a home in Girrawheen. She died two days later.
A 30-year-old man was initially charged with grievous bodily harm.
He will face Perth Magistrates Court on Monday and his charge will be upgraded to murder, WA Police said in a statement.
