Murder charge laid after Qld toddler dies

A Queensland father has had a grievous bodily harm charge upgraded to murder after his two-year-old son died in a Brisbane hospital.

The boy was flown to Lady Cilento Children's Hospital on Wednesday following months of alleged abuse at his 33-year-old father's hands.

He died on Friday night.

Earlier that day, the father appeared in court charged with four counts of assault occasioning bodily harm and one count of grievous bodily harm.

The latter charge has now been upgraded to murder, and a torture charge also laid.

The man, from Kin Kin, near Gympie, is alleged to have assaulted the boy on a number of occasions between December and March.

He did not apply for bail and was remanded in custody.

He is due to reappear in court on March 30.

It comes after 18-month-old boy died on Thursday from injuries he suffered in a separate assault, allegedly at the hands of a 29-year-old man.

The boy died in a Townsville hospital from unspecified injuries.
