VERO BEACH, Fla. — Authorities say a Florida teen has been detained after posting threats against a school on social media.

Treasure Coast Newspapers reports that the Vero Beach High School student was detained off-campus Monday.

An Indian River County school district spokeswoman says the student had been seen on campus but was later detained by sheriff’s deputies off school grounds. The sheriff’s office says no weapons were involved or recovered.

Officials say the high school and a nearby learning center were briefly placed on a precautionary status where classes proceeded normally but not a full lockdown.
