A student at Osbourn High School in Manassas, Virginia, was arrested after police say threats toward the high school and a neighboring elementary school were found on social media.
Manassas City police did not identify the 15-year-old student, but they say the suspect is a 9th grader at Osbourn High School.
Police say they were notified of the threatening Instagram post toward Osbourn High School and Baldwin Elementary School on Sunday. The post featured the image of an assault rifle, but police say the photo was taken from the internet.
Investigators have determined that the threat was not credible, and the student did not have the means to carry out the threat.
The student has been charged with two felony counts of making threats to commit serious harm to persons on school property. The teen is being held without bond.
Police believe the student acted alone, but there will be more police officers at both schools on Monday as authorities continue their investigation.
News of the arrest in Mannassas comes just fours days after officials in Montgomery County arrested an 18-year-old man and charged him with making threats against his former high school.
