A violent riot has broken out in Darwin's controversial Don Dale Youth Detention Centre.
Heavily armed police officers were called to the riot around 7pm on Tuesday night and within a few hours, a fire broke out.
There are reports of multiple people seen rioting, holding knives and rocks, while others threw objects at officers from the roof of the building.
According to the ABC, Police used a loudspeaker to urge inmates to put down their weapons and surrender.
Just after midnight, multiple detainees were spotted being taken from the centre in police vehicles, the ABC reports.
NT police were last month called to investigate after reports a group of detainees had caused damage and stolen keys.
The Don Dale facility made headlines in 2016 when Four Corners aired footage of teenage boys being assaulted, stripped naked and tear-gassed.
