Police in riot gear responded this morning to a local Miami high school after reports of a fight and possible gunshots inside the school.
Edison Senior High School students at the scene told ABC News' TV affiliate WPLG that a "disturbance" had broken out after a student protest organized in response to an unspecified incident that had occurred at the school on Thursday.
A few students were demonstrating at lunch around 11 a.m., Olga Bichachi told ABC News, when school resources officers responded to the disturbance and Miami-Dade police were called.
Rescue units arrived, and students could be seen in aerial footage in handcuffs being led from the school to a police paddy wagon. Several students were seen limping.
A few the officers suffered minor injuries, according to Bichachi, who added that it did not appear that weapons were involved.
The school remains in lockdown. Bichachi said the school district did not expect to announce an early dismissal, but parents would be allowed to pick up children early.
Rubberneckers along adjacent Interstate 95 paused to take in the scene from the highway, causing gridlock.
Edison recently celebrated its move from a designation of an "F" or failing school to "D." Last year only 10 percent of students met reading standards, according to the Associated Press. Less than a third met state math standards.
