The president of the Australian Human Rights Commission, Gillian Triggs, has called for an inquiry into juvenile detention after the ABC aired harrowing footage of apparent abuses of young people in custody in the Northern Territory. The program also prompted the leader of the NT, Adam Giles, to pledge he would seek advice on establishing a royal commission. The ABC's Four Corners program on Monday night aired footage of a 17-year-old boy, one of six boys tear-gassed at a juvenile detention centre near Darwin, being hooded and strapped to a mechanical restraint chair. The footage is part of a catalogue of evidence obtained by Four Corners of the repeated assault and mistreatment of boys at youth detention centres in the Northern Territory. Amnesty International has described the abuses carried out against children as shown in the Four Corners program as a violation of both the UN Convention on the Rights of the Child and the Convention Against Torture. Julian Cleary, Indigenous rights campaigner at Amnesty International Australia, called for an end to the systemic abuse of children in youth detention. To see a crying, distressed child seized by his neck, forced to the ground, manhandled, stripped naked by three grown men and left naked in a cell is just sickening," he said. "The footage of guards laughing at a child being tear-gassed and in distress defies belief." The NT has the highest rate of youth detention in Australia, and 95 per cent of detainees are Aboriginal.
