ANCHORAGE -

A 16-year-old boy is being held on child pornography charges in the Mat-Su Valley, following his Thursday arrest as part of a case under investigation in recent weeks by Alaska State Troopers.

According to a Friday AST dispatch, the teen was taken into custody without incident and remanded to the Mat-Su Youth Facility on charges of possessing child pornography.

“On (March 26) the Alaska Bureau of Investigation's Technical Crimes Unit contacted a (16-year-old) juvenile near Wasilla during an investigation into the distribution of child sexual abuse images using mobile devices on the MeetMe and Kik social networks,” troopers wrote. “Electronic devices were seized that were processed in the Technical Crime Unit's laboratory and evidence was found that corroborated the allegations.”

While AST spokesperson Megan Peters declined to give further details of the case against the teen Friday because he is a juvenile, she says troopers haven’t found any indication of a larger ring of people distributing photos.

“They don’t believe the case extends beyond him,” Peters said.

Terms of use posted at MeetMe’s website as well as Kik’s site bar users from uploading pornography, but both networks have been in the news this year after cases involving explicit materials. In February a Warwick, R.I. teacher was arrested after allegedly logging onto MeetMe as a 16-year-old girl and soliciting explicit photos from teenage boys, while Canadian officials warned of automated spam messages on Kik soliciting explicit material from users.

Mat-Su Borough School District spokesperson Catherine Esary said Friday afternoon that she hadn’t heard about any wider investigation into the Wasilla case. She emphasizes that district policy bars harassment or bullying of students by various methods, both online and offline.
