Child fighting for life after falling from third-storey unit window

A seven-year-old boy is fighting for life after falling from a window of a unit at Bankstown in Sydney's southwest last night.

About 7.20pm, the boy fell from a bedroom window of a third-floor unit on Chapel Road.

The boy was rushed to Bankstown Hospital by family members.

He was then conveyed to Sydney Children’s Hospital, Randwick, suffering critical head injuries.

Police have told 9NEWS they are investigating the circumstances surrounding the incident but it appears the boy had been playing before he fell.

More to come.
