A suspect in the shooting at Saugus High School is in custody and is being treated at a hospital, Los Angeles County Sheriff Alex Villanueva said on Twitter.
Details about how the suspect was captured weren’t immediately available.

. The suspect is believed to be a student at the school, Villanueva told CNN affiliate KABC
Of six patients taken to hospitals, one has died and two are in critical condition, hospital officials said. At least five were shot, a sheriff’s department official said.
Emergency workers took at least three people out of the school on gurneys, and large groups of people walked out single-file with armed escorts, aerial footage from CNN affiliates shows.
The shooting happened about 20 minutes before the start of school, according to Hannah de Caussin, whose daughter attends Saugus.
Some students fled, and others hid
Some students fled the building immediately, and others took cover inside rooms, another student told CNN affiliate KTLA.
“It was one and then four quick ones, so bang, and then bang, bang, bang, bang,” the student, a girl, told CNN affiliate KTLA, after leaving the building.
Students are trained to take cover in classrooms, but she and some others ran out because they thought the shooter was near where they would have hidden, she said.
