A 15-year-old boy was among four people injured in a car roll-over near Fitzroy Crossing this morning.
The teenager was a passenger in a Holden Commodore which rolled on Great Northern Highway, near the turn-off for the Muludja Aboriginal community, about 8am.
The incident left a 22-year-old man in a critical condition and he will be airlifted to Perth via the Royal Flying Doctor Service.
The boy suffered less serious injuries and was to be flown to Broome Hospital along with two other men, aged 18 and 23.
Police inquiries are continuing.
