A 4-year-old girl was clinging to her mum's leg when she was fatally mauled by a pitbull terrier in Melbourne's northwest.
The girl died from her horrific injuries and her two cousins were injured in the attack at a house in St Albans.
The dog is believed to have escaped from a neighbour's yard and entered the home where Ayen Chol and her 5-year-old cousin were playing.
Ayen died at the scene despite ambulance officers' attempts to revive her.
Daniel Atem, a cousin of one of the victims, said one of Ayen's relatives was outside the house when the dog came at her. As she rushed into the house, the animal followed her.
