Multiple fights were reported Tuesday at John C. Fremont High School in the Florence neighborhood of South Los Angeles, drawing a major police response and multiple ambulances.
No injuries were reported by the Los Angeles Police Department as authorities responded just before noon. LAPD Officer Rosario Cervantes said rocks and bottles were thrown in altercations at the campus, located at 7676 San Pedro Street.
Authorities later said a group of girls were fighting and the conflict grew from there.
Sky5 was over the high school around noon as two dozen LAPD patrol cars were wrapped around the block, surrounding the campus. A fire engine and two ambulances were parked outside the entrance.
First responders carried a stretcher into the front of the building as police officers stood guard in other areas.
In one spot on campus, aerial footage shows two dozen officers standing in a single row, holding what appear to be batons and facing students. Cellphone footage from inside the campus shows crowds of students pulling and shoving one another.
"It was two groups of kids fighting, going back and forth," said one student, who said she heard from others that a student's older brother brought weapons to the campus. "It was all just a fight and then it got bigger and bigger."
No other details have been released by LAPD.
