A 23-year-old man accused of killing his five-week-old baby son in Perth’s north-east has appeared in court.
Matthew Wayne Winmar was charged with manslaughter after allegedly inflicting serious injuries on the infant at a residence in Kiara on August 10.
He was taken to a nearby medical centre, before being transferred by ambulance to Perth Children’s Hospital.
The baby died on August 15 as a result of his injuries.
Mr Winmar was arrested at a home in Katanning yesterday, and was also charged with assaulting a woman aged in her 20s who was known to him.

He was charged with two counts of common assault in circumstances of aggravation or racial aggravation.
Both incidents are being treated as family violence-related.
Mr Winmar has appeared in Perth Magistrates Court and made no application for bail.
He is scheduled to appear in Stirling Gardens Magistrates Court later this month.
