Numerous 911 calls came in Friday morning about an incident at Highland High School. The school was placed on lockdown while police responded, a spokesman for the Palmdale Sheriff’s Station told HuffPost. The Bureau of Alcohol, Firearms, Tobacco and Explosives also responded to the scene.
A firearm was recovered and the detained suspect is a 14-year-old male, authorities said.
Meanwhile, an elementary school just seven miles away from Highland also had a police presence after reports of gunshots being heard. Authorities later gave an all-clear for Manzanita Elementary School.
