Cars have been torched before police used pepper spray to disperse an armed crowd amid ongoing unrest in a remote community.
Northern Territory Police on Thursday evening responded to reports of a disturbance in the Indigenous community of Wadeye.
It came after a man was shot in the arm with a crossbow during a brawl the previous day.
Three vehicles were set on fire in the township on Thursday and officers used pepper spray when the crowd of up to 100 people failed to comply with directions to disperse, police said.
Some people were allegedly armed with "edged and blunt weapons".
No serious injuries were reported but two men were arrested and multiple weapons were seized.
Police have scheduled a meeting with community leaders to reduce tensions.
"Those involved in the hostile conduct will be held to account," Acting Senior Sergeant Jimmy Yengayenga said in a statement.
Police also responded to a disturbance in the outback town of Yuendumu on Thursday evening, with up to 30 people involved in disorderly behaviour at a residence.
A man was allegedly assaulted, suffering facial injuries, and three vehicles were damaged.
Police dispersed the crowd with the help of community elders.
At Wadeye early on Wednesday police responded to reports of a clash involving up to 15 people.
The group was broken up, with a 34-year-old man later presenting at the health centre with a crossbow bolt lodged in his arm, police said.
He was taken to Darwin by a CareFlight aircraft for treatment of serious but non-life-threatening injuries.
Police believe the incident was linked to a dispute in the community that began on Monday, with a brawl watched by up to 100 people.
The Wadeye brawls follow recent unrest in the remote Arnhem communities of Maningrida and Ramingining.
Police said the early January fighting in Maningrida was driven by social media posts and retributions and involved more than 200 people, some armed with bladed weapons.
Officers made 10 arrests, including a 31-year-old man charged with recklessly endangering life after he sped through the community and allegedly nearly struck a police vehicle before crashing.
Just before Christmas brawls involving up to 40 people erupted in Ramingining, with several people injured and one man charged with aggravated assault.
