Police in Alice Springs remain vigilant as youth crime continues after an emergency curfew was imposed on the besieged town.

Several youths allegedly burgled a house on Thursday night, armed with a weapon and screwdriver, Northern Territory Police Commissioner Michael Murphy said.

“We have a team of detectives on that and we have some good footage identifying everyone else involved so we’re expecting some quick action on that,” he said.

Up to seven youths were involved in the incident and three are in custody, according to police.

Murphy said police received reports a camping stall was broken into by youths about 5am on Friday.

Chaos descended on the red centre town on Tuesday afternoon when a large group attacked the Todd Tavern, leaving a $30,000 damage bill, as tensions escalated between families following the death of a teenager.

Brawls continued later in the night as family members mourned the death, with up to 150 people clashing in town camps.

There were arrests and more than 50 weapons were seized, including spears, axes and clubs.

The Northern Territory government also declared an emergency two-week curfew, barring anyone under the age of 19 entering the Alice Springs CBD between 6pm and 6am.

Murphy said the move had brought some positive changes.

“This emergency situation and the action that has been undertaken has generated some positive discussion for a number of partners in the Alice Springs community, Central Australia and actually the nation,” he said.

The temporary curfew was backed by the federal government, with Prime Minister Anthony Albanese on Thursday calling it a “sensible move”.

“All Australians will be concerned by the scenes that we have seen,” he said.

However, Murphy said there was no need for extra federal assistance.

“Northern Territory police are more than capable of delivering public safety services to the community, and we will prove that,” he said on Thursday.

Rising tensions in the desert town were inflamed by the death of an 18-year-old in a fatal car accident in early March.

He died after hanging out of the window of a stolen car that rolled over in the Alice Springs CBD.

The youth was crushed and killed by the vehicle and left there by the driver and passengers.
