A Queensland Ombudsman report into the Brisbane Youth Detention Centre has found young detainees were isolated in rooms without beds, toilets or running water for up to 10 days after a 2017 riot at the facility.

The report said the seven detainees being held in so called “admission rooms” after a violent riot is a form of solitary confinement, with four of the detainees being kept in the rooms for the entire 10-day period.

The detainees had to sleep on mattresses on the floor and had to wait for staff members to escort them to the bathroom.

The admission rooms were designed to only hold newly admitted detainees temporarily, with investigators being told there was no choice but to house detainees in the temporary rooms because of extensive damage to other accommodation options during the riot.
