A policeman accused of murdering an aboriginal man in the Northern Territory has been identified as Zachary Rolfe.

The 28-year-old allegedly shot Kumanjayi Walker at home in the tiny desert town of Yuendumu, 300km north-west of Alice Springs, on Saturday night.

The incident happened after two police officers went to his house to arrest him for alleged breaches of his suspended sentence.

With no medics in the town, Mr Walker was taken to a police station but died two hours after he was shot.

Rolfe served in the Army before joining the police in 2016 and won The Clarke Medal (he is pictured collecting his medal with the Governor-General) of bravery for rescuing a woman from a flood waters in Alice Springs in December that year

Rolfe is the son of Canberra business identities Richard and Debbie Rolfe.

Richard Rolfe is the director of the Audi Centre in Canberra, a position he has held since 2007.

Zachary, who went to Canberra Grammar School like his father, served in the Army before joining the police in 2016.

Just days after graduating police training in December that year, he won The Clarke Medal of bravery for rescuing two tourists from a flood waters in Alice Springs.

NT Police confirmed an officer had been charged with murder on Wednesday night.

A statement read: 'A 28-year-old male Northern Territory police officer has been charged with one count of murder. As this matter is before the court, no further information will be released.'

Rolfe has been granted bail to appear in court in Alice Springs on 19 December.

The NT Police Association said it 'is continuing to support our member who has this evening been charged with murder, as well as his family, and all other officers involved in the critical incident at Yuendumu.

'The officer who has been charged is being provided all appropriate legal advice and support at this difficult time.'

Mr Walker's family were not told about his death until the morning after he was allegedly shot after believing overnight that he was still alive.

Angry residents from the remote community of about 800 Warlpiri people gathered after the alleged shooting at the police station as officers locked themselves inside.

NT Police Acting Deputy Commissioner Michael White said after the alleged shooting that Walker had lunged at an officer and stabbed him with a weapon, which sources had said were scissors and a struggled ensued, but the family disputed that version.

The officers had body-worn cameras that have been viewed by NT police internal investigators.

Mr Walker was released from prison on October 21 over property and stealing offences but was being re-arrested for breaching the terms of his release.

Police had allowed Mr Walker to attend the funeral of a relative earlier that day.

There were no medical staff to initially help after the alleged shooting as Yuendumu Health Centre workers evacuated earlier on Saturday due to safety concerns.

The Royal Flying Doctor Service also delayed its response amid safety concerns before it was called off because the young man died.

Staff from Yuelamu Health Centre 60 km away were injured after going to Yuendumu following the shooting and assisting in pronouncing Mr Walker dead.

They were injured in community unrest and required evacuation to receive treatment for lacerations and bruises at the Alice Springs Hospital.

Emotions are running high among Indigenous people in the NT and around the nation and the death has been a flashpoint for anger over the treatment of Aboriginal people by police, including deaths in custody, high prison rates, past massacres and the Stolen Generations.

The Northern Territory Chief Minister Michael Gunner and NT Police Commissioner Jamie Chalker flew to Yuendumu to assure people an independent investigation would be conducted.
