From the Pittsburgh Post-Gazette:

The arrest of a North-Central Pennsylvania man on internet child pornography charges spurred dozens of more arrests from Pittsburgh to Philadelphia, state police said.

Half of the 44 men arrested since the investigation began three months ago are from Western Pennsylvania counties or connected to cases on this side of the state.

Two agencies, the Internet Crimes Against Children task force and the State Police Computer Crime Task Force, began investigating after an agent detected Ronald Paul Bellows of Richmond, Tioga County, was online sharing child pornography with other men.

Armed with a search warrant at Mr. Bellows’ residence, state police arrested him on 15 child pornography counts.
