Colorado officials say they won't file criminal charges against a group of teenagers who exchanged a partially nude photo of a juvenile.

The Gazette reports that 4th Judicial District Attorney's office spokeswoman Lee Richards said Tuesday that a review of the case found nothing malicious in the teens' behavior.

The five Pine Creek High School and Challenger Middle School students could have faced felony charges.

Richards says the cellphones were reviewed and the images will be deleted before they are returned to their owners. She says the students will also be required to attend sexting classes run by the DA's Office.

School district spokeswoman Nanette Anderson would not say if any of the students had been suspended or expelled.
