A suspect is in custody after a shooting was reported on Friday morning (local time) at a Southern California high school.
Palmdale is in Los Angeles County, about 40 miles north of downtown Los Angeles.
Both Los Angeles County Sheriff's Department and the Palmdale Fire Department said they had received reports of shots being fired - the first coming around 7am local time.
The sheriff's office tweeted one suspect has been detained in connection to "the person with a gun...at Highland High school in Palmdale."
The school's principal took to Twitter, appealing people to stay away from the campus.
"Law enforcement is working to assess the situation," the message from Principal Chris Grado says. "Please stay clear of campus. Will update as soon as have more information."
Highland as well as three other schools in the local area have been placed on lockdown, according to several media reports.
An investigation is underway.
