Teens here are taking nude photos of themselves or others, sending them on their cell phones or posting them online.
Some teens do it as a joke.
Three teenage girls who allegedly sent nude or semi-nude cell phone pictures of themselves, and three male classmates in a Greensburg Salem High School who received them, are charged with child pornography.
Police said the girls are 14 or 15, and the boys charged with receiving the photos are 16 or 17. None are being identified because most criminal cases in Pennsylvania juvenile courts are not public.
"It was a self portrait taken of a juvenile female taking pictures of her body, nude," said Capt George Seranko of the Greensburg Police Department.
Police said school officials learned of the photos in October. That's when a student was seen using a cell phone during school hours, which violates school rules. The phone was seized, and the photos were found on it, police said. When police investigated, other phones with more pictures were seized.
"Taking nude pictures of yourself, nothing good can come out of it," said Seranko.
The Greensburg Salem School District issued a statement on Tuesday saying there was "no evidence of inappropriate activity on school grounds or during the school day other than the violation of the (school's) electronic devices policy."
The school district said it only became aware of the arrest of the students on Monday and will continue to work cooperatively with police, as well as continue to enforce its electronic devices policy and educate students on the dangers of inappropriate use of electronic devices.
Police said the girls are being charged with manufacturing, disseminating or possessing child pornography while the boys face charges of possession.
"It's very dangerous," said Seranko. "Once it's on a cell phone, that cell phone can be put on the Internet where everyone in the world can get access to that juvenile picture. You don't realize what you are doing until it's already done."
