Those suspects were identified by the Pennsylvania Attorney General's Office as Daniel Bruce Clark, 32, of Perkasie, Bucks County and Peter M. Medve, 32, of Seneca Street in Bethlehem, Northampton County.
Investigators say, in both cases, they tracked their computers' IP addresses from a peer-to-peer file sharing network, allegedly used to share media depicting suspected child porn.
Clark is charged with 50 counts of possession of child pornography and was released on 10 percent of $250,000 bail. Medve is charged with 315 counts of possession of child pornography and was released after posting 10 percent of $150,000 bail.
The arrests also include that of 59-year-old Christopher Eaken, a Blair County man who was arrested following an investigation that started in Canada.
The AG's office said an investigator with the Royal Newfoundland Constabulary in Newfoundland, Canada, was posing as a 13-year-old girl in an online chat room. Investigators say Eaken asked for nude photos, and for the "girl" to change her profile to say she was 18 years old.
Eaken was charged with unlawful contact with a minor and was held on $50,000 bail.
