A teenager held in Western Australia's notorious Unit 18 youth detention facility was taken to hospital Friday after being found with fabric wrapped around his neck.
The 17 year-old was found by guards with fabric around his next and a small cut to his neck around 10am, Nine News reported.
St John Ambulance took the boy to Fiona Stanley Hospital where he remains under the care of medical staff.
It is understood his injuries are not life-threatening and on Friday he was undergoing medical treatment and a mental health assessment.
The boy's self-harm came on the same day more systemic failures surrounding the death in custody of Unit 18 detainee Cleveland Dodd in October were revealed, and as more than 100 justice, human rights and health experts urged WA Premier Roger Cook to close the facility.
On Friday it was revealed staff at the controversial youth unit at Casuarina maximum security adult prison were watching a film when Cleveland self-harmed, leading to his death days later, after the day previous it had emerged that a senior prison officer had likely been asleep at the time of the suicide attempt.
On Friday Corrective Services Minister Paul Papalia said the "concerning nature" of the findings of the interim internal inquiry had prompted him to release a redacted version of the document.
Amnesty International Australia and said last month Mr Cook and Mr Papalia "ignored repeated warnings" that the children incarcerated at Unit 18, located in maximum security adult prison Casuarina, experience "intolerable levels of distress, putting their safety at risk".
The human rights watchdog also noted there have been more than 500 incidents of young people attempting suicide or self-harm in WA's juvenile detention system over the past two years.
