A woman, 42, has been arrested by detectives from the strike force investigating alleged sex assaults and grooming of students at a Sydney dance studio.
It will be alleged she took inappropriate photos of her two daughters, who were under 14 and students at the inner west dance studio, and distributed them to another person.
The woman was arrested at 10am (AEST) on Wednesday after attending Burwood Police Station.
She's been charged with two counts of using a child under 14 for the production of child abuse material and disseminating child abuse material.
Dance teacher Grant Davies has already been charged with a number of offences arising from the investigation.
