An Issaquah High School student was arrested Sunday night after police were notified that the girl had posted a video on the social media platform TikTok that contained “inappropriate and threatening language.”

The high school reported to police that a student had posted a possible threat of a school shooting, Issaquah police spokeswoman Paula Schwan said Monday afternoon. The video was viewed on TikTok, a mobile app where users create and share short-form videos.

Police worked in cooperation with the school to arrest the student, who lives in Issaquah. Her family members were cooperative with law enforcement and the investigation, Schwan said. Officers didn’t locate any weapons, nor “were there any available means to carry out a threat.”

She was booked into the King County Juvenile Detention Center and faces felony harassment charges, according to the city’s statement.

“Issaquah police take these types of incidents – and the safety of students and staff – very seriously,” the city’s statement said. “The school will be functioning normally this week.”
