Authorities say two students at Marjory Stoneman Douglas High School brought weapons on the school's campus, and a third is accused of making a threat on social media.
Arrest reports from BSO say two students brought knives on campus.
Jordan Salter, 18, and Gavin Stricker, 16, were arrested in separate incidents at the school on Tuesday.
Salter was arrested for bringing a weapon on campus after, deputies said, she showed a 2-inch knife during a confrontation with a male classmate in the cafeteria, Tuesday morning.
At around 10 a.m., BSO deputies were called back to the school on a report that a 10th-grader allegedly made threatening posts on social media directed at a classmate.
According to the arrest report, the student was pulled from class after “posting pictures on Snapchat depicting a handgun in his waistband and numerous bullets,” along with threatening messages.
He was eventually taken in for a psychiatric evaluation.
And just after school let out Tuesday afternoon, Stricker was taken into custody after, deputies said, “a 9-inch knife was found in his backpack.”
Deputies said a student told a teacher that Stricker had been brandishing a knife on the bus on Monday.
Hours later, Stoneman Douglas Principal Ty Thompson sent a recorded message that stated, “Earlier today, we had three incidents on campus that required law enforcement intervention. Due to student privacy laws, I cannot disclose the details of these incidents.
"However, in all three cases, the individuals involved will receive the appropriate consequences through the juvenile justice system and the district’s code of student conduct.”
