Story highlights TV news report alleges widespread abuse at Northern Territory juvenile detention center

Prime Minister Malcolm Turnbull says revelations left him "shocked and appalled"

(CNN) Australian Prime Minister Malcolm Turnbull has called for a national investigation into allegations of abuse and torture at a juvenile detention center.

The allegations, which appeared on Australian Broadcasting Corp.'s " Four Corners " investigative program, showed children as young as 10 being stripped naked, assaulted, tear-gassed and kept in solitary confinement.

"Like all Australians, I have been deeply shocked, shocked and appalled, by the images of mistreatment at the Don Dale center" in Darwin, the capital of Australia's Northern Territory, Turnbull said.

"We will get to the bottom of what happened here. ... We want to know why there were inquiries into this center which did not turn up the evidence and the information that we saw on 'Four Corners' last night.' "

Turnbull said he had met with the Northern Territory Chief Minister Adam Giles and Australian Attorney-General George Brandis.
