The Northern Territory police team involved in the shooting death of an Indigenous teenager weren't authorised to carry out the arrest that led to the incident, a top-ranking officer says.
Kumanjayi Walker, 19, died after Constable Zachary Rolfe shot him three times while attempting to take him into custody in Yuendumu, northwest of Alice Springs on November 9, 2019.
Assistant police commissioner Travis Wurst told an inquest into the Warlpiri man's death that he approved a plan to send members of the immediate response team to the outback community to help exhausted local officers with general duties, not arrest Mr Walker.
