ETIWANDA, Calif. (KTLA) — They are nude self-portraits, taken by teenage girls, now on display in cyber space for everyone to see.

A sophomore boy at Etiwanda High School who tweeted nude pictures of at least four underage girls at nearby Rancho Cucamonga High created more than teenage Twitter drama.

His actions have now led to a criminal investigation.

The San Bernardino County Sheriff’s Department is investigating the incident as a suspected case of child pornography.

But it’s not just the teenage boy who tweeted the nude photos who may have committed a felony, according to a department spokesperson.

Any underage girl who takes a nude self-portrait and texts it from her phone is committing the same crime.

Fellow students believe the boy collected the nude pictures from the girls’ ex-boyfriends, then sent them out in order to gain popularity on Twitter.
