A 15-year-old student at George Mason High School in the City of Falls Church was arrested Monday after school staff found a list he wrote with names and plans to cause harm to people at the school, police reported Tuesday evening.

Police say the note was found on Monday by school staff who then turned the note over to police. The suspect was removed from class and arrested and police searched his home. While the police determined the threat was credible, they said there was no immediate threat to the school or the community.  The juvenile has been charged with threats to harm people on school property.

In a press release, City of F.C. Police Chief Mary Gavin said “The City of Falls Church Police are grateful for the school administration and our School Resource Officer who acted swiftly. It allowed us to intervene in a timely manner. We take these threats seriously. The courage of people coming forward is key in keeping our community and schools safe.”

The suspect was arraigned Tuesday at Arlington County Courthouse but the arraignment has been continued to next Tuesday, March 13, pending further evaluation of the juvenile.
