An Anchorage School District student has been arrested after police say he posted a threat against going to school on social media.

The Wednesday threat, police said in a statement, involved “a photo on social media of several guns from inside a store gun case.”

“In the post, the student made a threatening warning [not] to attend school today,” police wrote. “Several students saw the threat last night and called dispatch to report it.”

ASD's superintendent, Dr. Deena Bishop, thanked the students who came forward to report the threat in an email sent to all district parents and posted to the district's Facebook page.

"We appreciate the students, families, and staff who came forward to share this information," Bishop wrote. "It allowed us to deal with this situation swiftly to ensure the safety of our schools."

After speaking with the juvenile student who made the post, police determined that there was “no active threat to schools today.” The student was arrested and held at the McLaughlin Youth Facility, with charges forwarded to the state Division of Juvenile Justice.

APD spokesman MJ Thim was unable to discuss the suspect’s age or which school he attended, but said no particular school was named in the threat.

"Here's a picture of some guns and some text below: 'Don't come to school tomorrow,'" Thim said. "The students felt their lives were threatened and called us."

Thim warned students against making similar posts.

“If you are joking around or not, they are serious threats and they are taken very seriously,” Thim said.
