The school in California shooting occurred

Highland High School in Palmdale California

This is reportedly the 21st school shooting in the USA this year.

Just after 9 a.m., Los Angeles County sheriff's deputies confirmed that Highland High School had been cleared; the lockdown was lifted about 90 minutes later. The teen was in her Reserve Officers' Training Corps class, and said students were putting sofas and desks in front of the classroom door and windows to barricade themselves inside, Luke said. "The student said he was only joking, but deputies later found two semiautomatic rifles, two handguns and 90 high-capacity magazines at the student's home".

The victim, a 14-year-old boy, was hit in the arm and was in stable condition at a hospital.

Witnesses who were outside the school described hearing a gunshot or gunshots, and seeing students running from the building.

Parents and students were outside the school crying as investigators remained on campus. A 14-year-old male student was taken into custody during a massive law enforcement response following the campus shooting that left one student with a gunshot to the arm.

Firefighter-paramedics told NBC Los Angeles they received a report of one person with a gunshot wound, though any injuries couldn't be independently confirmed.

"But if they would've said it was still happening, I would have run here", he said.

Officials say a 14-year-old high school student used a rifle to shoot a classmate at their high school in the California city of Palmdale and dumped the gun in the desert before he was caught at a nearby shopping center.

"We barricaded the room", she said.

Additional reporting from Newsy affiliate CNN. While police searched for the suspect and secured the area, the school was on lockdown. He said he heard one shot and turned.

The Bureau of Alcohol, Tobacco, Firearms and Explosives has also responded to the scene.

One person has been injured in a shooting at a California high school amid multiple reports of a gunman on campus. Two other students were grazed by bullets.

The 911 calls included reports that hostages were being held in the school library, Los Angeles County Sheriff Jim McDonnell said in a press conference Friday afternoon.

The deadliest school shooting this year was on February 14, when a former student killed 17 students and staff at Marjory Stoneman Douglas High School in Parkland, Florida.
