TAMPA, Fla. (WFLA) — Two Parrish Community High School students were arrested Thursday after posting separate, but similar videos “depicting a mass shooting on campus,” authorities said.

The arrests marked the third time students were arrested in the last two days for posting a video depicting a mass shooting, and the fourth threat to come out of the county in three days.

On Wednesday, Manatee County deputies arrested a student at nearby Buffalo Creek Middle School for posting a similar threatening video. A day earlier, an unknown person submitted a bomb threat to Parrish Community High School via the FortifyFL app, a suspicious activity reporting tool.

While there was no bomb, authorities said two students who attend the high school posted “separate, but similar” threatening videos as the school building was evacuated.

One student was arrested at their home early Thursday morning while the other student was located in a classroom and arrested on site.

Both students allegedly admitted to making the videos and were charged with the second-degree felony of making written or electronic threats to kill, do bodily injury, or conduct a mass shooting.

Deputies said they continue to investigate leads on multiple cases involving school threats.
