A Northern Territory police officer was caught on tape grabbing, shoving and verbally abusing a teenage boy in the Alice Springs watch house.

Footage obtained by the ABC shows highly inappropriate police conduct in the handling of a group of Indigenous boys arrested for stealing a car and leading police on a chase. 

The incident took place in March 2018, less than six months after the end of a royal commission sparked by revelations of mistreatment of young people in the Northern Territory's youth detention system.

The head lawyer at the North Australian Aboriginal Justice Agency, David Woodroffe, called on NT Police to condemn the incident but they refused to do so.
