In August 2014, six boys were in solitary confinement cells in the Behavioural Management Unit. One boy walked out of an unlocked cell, and beat on a locked reinforced door. The staff declared that there was a "riot", and released tear gas into the hallway, gassing all six boys. It took up to eight minutes to remove the boys in their cells from the tear gas. A news release to the media falsely asserted that six boys had escaped from their cells, despite CCTV in the hallway showing only one boy in the hallway. The incident, among others, was investigated by the Northern Territory Children's Commissioner Colleen Gywnne in a report provided in August 2015 to the then Corrections Minister John Elferink.
