A Ukranian man charged by federal authorities with running a worldwide child pornography distribution network has made his first appearance in a New Jersey courtroom.

The U.S. Attorney's office says Maksym Shynkarenko (max-SEEM' shank-AH'-rank-oh) from Kharkov, Ukraine, founded and operated a Ukraine-based child pornography website that had customers around the world and has resulted in 560 convictions of customers in the U.S.

Shynkarenko was extradited from Thailand over the weekend to face a 32-charge indictment.

A federal judge in Newark on Monday ordered him to remain in custody pending his arraignment Wednesday.

The 33-year-old Shynkarenko, wearing green prison scrubs, close-cropped hair and glasses answered a judge's questions in English that he did understand his rights. He has been assigned a court-appointed attorney.
