On Feb. 12, the mother of one of the girls called police to report a nude picture of her 18-year-old daughter being posted on the internet. The woman said the photos were from when the teen was 14 or 15 years old.
The victim said pictures of other teens were posted on the same Instagram account and others. The images include photos of breasts and genitals, along with photos of oral sex.
The search warrants say Wake County School System security personnel were able to identify the teens, both girls and boys, in the pictures as students at Enloe High School, Athens Drive High School, Rolesville High School, Holly Springs High School, Heritage High School, and Middle Creek High School.
The search warrants seek more information on the Instagram accounts involved and user data.
Wake Forest public information office Bill Crabtree asked parents to be vigilant.
"We are urging parents and guardians to take this opportunity to educate their children on the dangers of posing for inappropriate pictures; taking inappropriate photos of themselves, distributing inappropriate photos through email or text, and/or posting inappropriate pictures online," Crabtree said.
"I just think that it's a travesty that people would do something like this," said parent Felise Knight-Lucas. "It's just really sad that someone would take something like that and post it and of our minors and just take into account how it could affect their lives now as well as in the future."
Apparently, many students knew about the naked pictures and circulated them on-line.
Based on what ABC11 has uncovered on Twitter, Wake County Schools officials knew about the photos as early as six days ago.
Wake County School Board Chair Christine Kushner declined to comment on camera Tuesday.
Tuesday afternoon, the school district did issue a statement which read, "The Wake County Public School System is working with law enforcement as it investigates criminally inappropriate use of photographs involving Wake County students. The school district takes such actions seriously and will assist investigators in any and all efforts to identify and prosecute offenders."
