Two Pennsylvania men, including a 53-year-old from Philadelphia, are accused of downloading images depicting children engaged in graphic sexual acts, according to the Pennsylvania's Office of the Attorney General.
William Bairstow of the 300 block of Hellerman Street in the city's Lawndale section was arrested in late July after an undercover investigation revealed he allegedly disseminated child pornography online.
Authorities tracked graphic files shared on a peer-too-peer network to the IP address of Bairstow's computer, according to the Attorney General's Office.
The investigation uncovered several thousand videos and images containing suspected child porn on the suspect's computer, according to officials.
Twenty-four-year-old Alexander Park of Lemont, Centre County was also taken into custody for uploading pornographic images of minors, according to authorities.
Park uploaded the files, which showed juveniles engaged in graphic sexual acts and poses, to two separate websites, according to investigators.
Both suspects were released on bail. A preliminary hearing for Bairstow is scheduled for Aug. 14 and Park is due in court Aug. 6.
