A man has been struck with a three-pronged spear in a remote community disturbance involving about 100 people, police say.
A vehicle was also set alight after allegedly being surrounded by an armed group in the latest incident at the troubled township of Wadeye, 395km southwest of Darwin.
The 22-year-old man suffered serious injuries after being struck in the back by the spear during the disturbance between two family groups on Monday night, police said.
