Remember kids, sexting is illegal! A 16-year-old Rancho Cucamonga boy was arrested today for sharing nude pictures of four underage girls and now faces a felony charge.

The investigation into the high school sexting scandal began two weeks ago, when police were alerted that nude photos of girls from Etiwanda and Rancho Cucamonga high schools were being distributed on social media NBC reports.

The girls texted nude photos of themselves, which the male student then posted to Twitter, authorities say.

The 16-year-old boy, who attends Etiwanda High school, was held at juvenile hall on a felony charge, police said. He's also been suspected, natch. A 14-year-old girl who was also involved was issued a misdemeanor citation.

One student who's a friend of the boy told NBC, "I don't understand why he would do that. He doesn't seem like the person to do that."

“Rancho Cucamonga Detectives want to remind people of all ages that anyone who sends obscene images of persons under the age of 18, whether it’s of themselves or someone else, are violating child pornography laws,” San Bernardino County Sheriff’s Dept. Spokesperson Cindy Bachman told KNX1070.

Detectives are still trying to identify two of the girls in the photos. If you know anything about the incident, you're urged to contact the Rancho Cucamonga Detective Division at (909) 477-2800.
