USA Today: Dozens arrested in online child porn ring

More than 50 people have been arrested and 16 child victims identified in a two-year investigation of a global child pornography ring, U.S. officials said Wednesday.

Known as Operation Nest Egg, the investigation focused on a password-protected Internet bulletin board group that traded pornographic images of children. [...]

At its peak, the group had more than 1,000 members trading millions of sexually explicit images. U.S. officials took the website down in 2008, Assistant U.S. Attorney Steve DeBrota said.
