A New York Boy Scouts leader was arrested Wednesday after authorities found hundreds of images of pornography on his computer involving children as young as five years old, officials said.

Edward Orenchuk III, of Garden City, N.Y., was charged with three counts of promoting a sexual performance by a child as a sexually motivated felony and three counts of possessing a sexual performance by a child, according to the Nassau County District Attorney's Office.

Investigators observed Orenchuk making multiple images of child pornography available for download online during August and September, and they tracked the source of those images to his home, said Nassau County District Attorney Kathleen Rice.

Orenchuk himself indicated that he had hundreds of images of child pornography on his computer while his home was being searched, the district attorney's office said.

Orenchuk was an Eagle Scout who served as an assistant scout master with Troop 243 in Garden City. He was employed as a page at the Garden City Public Library.

The Boy Scouts said Orenchuk was dropped from the organization once they learned of the charges, the Associated Press reported, and a library spokeswoman said Orenchuk has been taken off the library's work schedule..

In mid-October, lawyers published more than 1,200 formerly secret Boy Scouts’ files online detailing accusations of child sex abuse within the organization from 1965 to 1985.
