Editor's note: All charges against seven co-accused were dropped in February 2020.

A group of men and women from a Blue Mountains circus training school have been charged with the alleged ongoing sexual and physical torture of three boys over two years.

Four women, two men and a 17-year-old girl have been charged with 127 offences relating to the alleged sustained abuse that occurred between 2014 and 2016.

Police confirmed to Fairfax Media that the seven alleged offenders were involved in a Katoomba circus training school called The Arcade Circus that catered to children with and without disabilities.
