Youth solitary confinement inquiry in Vic

Victoria's Ombudsman has launched an investigation into the solitary confinement of young people in youth detention with a view to improving rehabilitation rates.

Deborah Glass on Thursday announced she would use the United Nations' Optional Protocol to the Convention against Torture - ratified by the Australian government but yet to be implemented in Victoria - as the basis for her probe.

"If we are serious about protecting vulnerable young people and rehabilitating those in detention, we must ensure they are treated decently and with respect for their human rights," she said in a statement.

The investigation, instigated by Ms Glass's "own motion", will include inspections of solitary confinement facilities across Victoria and comparison to overseas models.

"Inspections are forward-looking and seek to improve and prevent," Ms Glass said.

"Inspections help to ensure the effectiveness of facilities in promoting rehabilitation, which in turn reduces recidivism and increases community safety. They can identify pressure points, which if left unchecked, can result in riots."
