Police have charged a 16-year-old boy with assault after two other teenagers were injured in a fight at a party in Sydney’s inner-west.

Officers say they found two 17-year-old boys with injuries after being called to a home in Five Dock where a fight had broken out.

One of the victims was found with stab wounds to the chest and side. He has had surgery and remains in a critical but stable condition in hospital.

Another teen had been hit in the head with a bottle and was treated for head injuries.

Police have since charged a 16-year-old with assault occasioning actual bodily harm and affray.

He has been given conditional bail and is expected to face a children’s court later this month.
