Prosecutors say Kenneth Schneider of Berwyn began a long relationship with a Russian boy when the victim was 12. They say he paid for the boy's ballet school and had the boy move in to his Moscow apartment.
The 45-year-old Schneider has been in custody since his March arrest in Cyprus. He is the founder of the Apogee Foundation, a New York-based arts group.
Schneider is also charged with bringing the boy to Philadelphia for a 2001 summer program and continuing the sexual relationship.
Defense lawyer Joseph Green Jr. tried unsuccessfully to get the charges dismissed on statute-of-limitation grounds.
