 A single dad in Mahopac secretly videotaped his son's 9-year-old friend in a swimming pool changing room, while a Westchester Medical Center nurse had 19 videos of children under 13 having sex with adults, authorities said Thursday as new details emerge about a regional crackdown on Internet child pornography. A poster board displayed photos, names and occupations of five men arrested as part of the operation: Brian Fanelli, a former police chief; Samuel Waldman, a rabbi; Yong Wu, a police officer; Jonathan Silber, a Boy Scout leader and Little League baseball coach;and Aaron Young, a paramedic. Special Agent in Charge James T. Hayes Jr., head of the New York office of Homeland Security Investigations, speaks about Operation Caireen, which resulted in the arrests of 70 men and one woman on child porn charges over the past five weeks Jonathan Bandler 
 
 Dubbed "Operation Caireen," the crackdown was headed by the U.S. Immigration and Customs Enforcement agency and was prompted in part by a probe of then-Mount Pleasant Police Chief Brian Fanelli, who was arrested in January and charged with downloading and distributing 
 
 child pornography. I was shocked," said Vic Robbins, 66, a retiree who lives across the street. "Clearly, this criminal activity has reached epidemic proportions." Gardner, who is married, is charged with possessing and prompting a sexual performance by a child, according to a complaint filed by the Queens District Attorney's Office. The current investigation – named for Caireen, the protector and patron of children in Celtic mythology – focused on online peer-to-peer, or "P2P", file-sharing that allows Interenet users to exchange images and videos. He said he began looking at child porn as research for the classes and that it grew into a "personal interest." Fanelli was freed on $50,000 bail after appearing in federal court to face child pornography charges, hours after federal agents raided his Mahopac home and seized computers containing more than 120 files of children as young as 7 years old engaging in sex acts. Investigators say they caught Fanelli by using software available only to law enforcement that identifies IP addresses of computers that have downloaded files known to be child pornography. He has been a licensed registered nurse since 1986, having worked at New York Hospital before moving to the Valhalla medical center in 1992. He was freed on $50,000 bail after appearing in federal court to face child pornography charges. Twitter: @jfitzgibbon, @corcoranterence, @alextailored, @leehiggins, @jonbandler, @reporterhoa

– More disturbing details are emerging about this week's huge child-porn bust in the New York City area, including these: a dad secretly filmed his son's friend, 9, when she changed to go swimming; a nurse had 19 videos of kids under 13 having sex with adults, authorities say. Another man, whose father was deported in 2008 after flying to Chicago in hopes of having sex with a 14-year-old girl, is charged with having images of girls as young as six, the Journal News reports. As for the Boy Scout leader and Little League coach, Jonathan Silber, 42, authorities say an IP address connected to the father of two was used to distribute child pornography online. "Surprised? I was shocked," said one of Silber's neighbors. "He's always got kids at his house. He's very active in the community … I would never have any suspicion that anything wasn't normal." Others charged in "Operation Caireen" (a nod to the protector and patron of kids in Celtic mythology) include a mother charged with producing pornography involving her own child, USA Today reports.
