Authorities are investigating social media threats over the weekend against several Broward County schools and have made at least one arrest, officials said Monday.
Broward County public school officials said a student was arrested for one of the incidents and an investigation is underway to identify all responsible for the threats.
According to an arrest report, the student threatened to shoot at Miramar High School during a group discussion.
The 15-year-old student, whose brother attended Miramar High School but attends another school, later told police she made the threat as a joke, according to the report.
District officials did not say what other schools were involved, but Fort Lauderdale Police officials said they were investigating threats against Dillard High, Stranahan High and William Dandy Middle School.
Security and police presence increased in schools as threatening posts were investigated, officials said.
“We want to assure our families and our community that all threats, including messages of a threatening nature on social media, directed at any staff and students are taken seriously and will be fully investigated. “Broward County Public Schools said in a statement.
