A student dressed in dark-colored clothing brought a gun to Gardena High School today and opened fire, injuring at least three people and prompting a massive police search of the campus.

The campus was placed on lockdown after the shooting, which occurred around 10:40 a.m. at the school at 1301 W. 182nd St. Gardena police Lt. Steve Prendergast told CBS2 a teacher called 911 to report the shooting. He said the severity of the injuries was unknown. At least two victims could be seen being loaded into ambulances.

It was unclear if the victims were students.

The suspect, who was described by Prendergast as wearing black clothing, remained at large. Officers from the Los Angeles Police Department, Gardena police and Los Angeles Unified School District police were scouring the campus in search of the suspect, who may have been a 16-year-old student.

Gardena High School has at least 2,600 students.

UPDATE: The Los Angeles Times reports the student involved in that shooting at Gardena High School is holed up in a classroom at the campus. LAUSD spokesman Robert Alaniz tells CBS2 the student brought a gun to the school in a backpack, and the weapon may have discharged accidentally.

LAPD says shooter in custody.

LAUSD spokesman Robert Alaniz tells ABC7: “Our indication is that a student took a gun to school in a backpack, and that that student had dropped the backpack and consequently the gun discharged. We’re not quite sure how both the students were injured, but we do know we have two injured students transported to the hospital.”
