The family of an Indigenous teenager who died after self-harming in youth detention say they are overwhelmed with grief that he died in a place "he did not belong."

Officers discovered 16-year-old Cleveland Dodd at the troubled Unit 18 youth detention facility at Casuarina Prison in Western Australia in the early hours of October 12, after he contacted them through the intercom.
