INDIANAPOLIS (AP) – Federal prosecutors in Indianapolis say they've dismantled a pornography ring that exploited nearly 100 children around the world and used sophisticated data encryption software to evade detection for 12 years.
 
They said Thursday that 11 men from seven states including Indiana have been convicted or are in custody. Others are charged or under investigation in Canada, Switzerland and other nations.
 
Assistant U.S. Attorney Steve DeBrota says the victims were mostly boys ranging from toddlers to teenagers. He says members of the ring mostly traded pornography instead of producing it. The largest individual collection had 18 terabytes, or 18 trillion bytes, of images. 
 
Prosecutors say some ring members held information technology jobs, and more tech-savvy members of the group coached the less tech-savvy in the secrecy needed to evade detection.
