Child porn: Ukrainian pleads not guilty in US

A Ukrainian man charged with operating a vast network of child pornography websites has pleaded not guilty in federal court in the U.S.

A court-appointed attorney for Maksym Shynkarenko entered the plea Wednesday.

The 33-year-old faces 32 counts for allegedly operating Ukraine-based child porn sites and selling access to clients worldwide. He was extradited to the U.S. because federal prosecutors discovered the websites on a computer in New Jersey.

New Jersey's U.S. attorney calls Shynkarenko the most significant distributor of child porn ever prosecuted in the U.S. Prosecutors say 560 U.S.-based customers have been convicted.

Ukraine's Foreign Ministry says it has found no evidence he committed a crime.

Shynkarenko remains in federal custody. Bail has not been requested.
