A young man faced a judge after, police said, he brought a gun to a high school campus in Margate.
Jalen Lindo appeared in a Broward County bond court on Wednesday, one day after the 18-year-old was arrested.
Investigators said the suspect brought a gun to SunEd High School, located along Banks Road.
Lindo faces charges of possession of a firearm on school property, carrying a concealed firearm and interfering with school administrative functions.
It remains unclear whether Lindo was a student at the school or whether he randomly appeared on campus.
