California police were hunting for the suspected shooter who reportedly opened fire at Saugus High School on Thursday, injuring at least six people — one of whom required CPR by emergency responders, officials said.
A "male Asian suspect" wearing black clothing was last seen walking away from the scene, the Los Angeles County Sheriff's Office said. Authorities warned residents to "please avoid the area."
Investigators said they would be locking down area schools as they searched for the suspected gunman.
It was not immediately clear if the shooting occurred inside the school building, on school grounds or near the school. It also wasn't clear what time the shooting happened, but a lieutenant with the fire department told Fox News school began at 6:55 a.m.
"Deputies on scene and still responding," the department tweeted. "Avoid the area Further information to follow."
Saugus High School is located 40 miles northwest of Los Angeles.
