An Olympian High School sophomore was arrested Wednesday on suspicion of making a threat on social media, Chula Vista police confirmed.
In her Instagram post, the 10th grader threatened a school shooting, police said.
Olympian HS officials contacted police on Wednesday after they saw the threat on Instagram.
Officers went to the student's home and interviewed her and her mother. Both were cooperative of the investigation.
The student admitted that she made the threat, but told police that she made it as a joke and thought it would be funny.
Officers searched the girl's house and found no weapons. She was taken into custody and transported to Juvenile Hall.
"The Chula Vista Police Department takes all school threats seriously, regardless of the intent or the ability of a person’s ability to carry out the threat at that time," the department said in a release detailing the incident.
