The Australian Center to Counter Child Exploitation (ACCCE) and Australian Federal Police (AFP) on Wednesday released images of items extracted from the backgrounds of sexually explicit materials to the public for the first time in the hope that the community can identify victims of abuse. The Australian initiative, "Stop Child Abuse - Trace an Object", gives the community an opportunity to help law enforcement personnel crack cases that are yet to be solved, according to Home Affairs Minister Peter Dutton.
