High School Student Brought Loaded AK-47 To School: Police

A 17-year-old student allegedly brought three loaded guns, including an AK-47, and a knife to his Texas school Monday morning.

James Madison High School in San Antonio, Texas, was placed on lockdown until the unidentified student, who also had additional ammunition in his backpack, was taken into custody. No injuries were reported at the school of over 3,200 students, according to The Associated Press.

KSAT News reports the boy's parents woke up Monday and discovered that their son and three of their guns were gone from their home. When they went to his school, they found their son on campus and then sat down with administrators, at which point they checked his backpack and discovered the ammo and two of the three guns. A third gun was found in a bathroom trash can, the San Antonio Express-News reports.

North East Independent School District spokeswoman Aubrey Chancellor said it is unclear exactly what the student planned to do with the weapons.

"The student had said that he planned making some demands over the announcements later today at Madison High School," she told local outlet KSAT Monday. "He didn't say specifically what those demands were, but he did say if those demands were not met, he had planned on committing violence."

Monday's incident comes days after workers at a nearby school district received an anonymous threat via email that said a mass shooting would take place last Thursday, according to San Antonio Express-News.
