WATCH: Principal Gets Shot Tackling Gunman at Oklahoma High School

A high school principal in Oklahoma is being called a hero after CCTV footage captured the moment he charged at an active shooter and tackled him to the ground, taking a bullet to the leg in the process.

The incident happened April 7 at Pauls Valley High School, approximately 60 miles south of Oklahoma City. Victor Lee Hawkins, 20, walked into the school lobby armed with two semiautomatic handguns, ordered everyone to the ground and attempted to open fire on students.

When Hawkins opened fire on a student and missed, Principal Kirk Moore burst out of a nearby door and tackled him from behind, pinning him face down on a bench. A staff member arrived to help restrain Hawkins and remove the gun from his hand. Moore was shot in the leg during the confrontation but held on until authorities arrived.

Hawkins was arrested on the scene.

Update on Investigation of Oklahoma School Shooting

According to an arrest affidavit, Hawkins — a former student — took two firearms belonging to his father without permission and arrived at the school with clear intentions of opening fire. Investigators said Hawkins told them he "wanted to conduct his own school shooting like the Columbine shooters," referencing the 1999 massacre in Colorado. He admitted his intention was to kill students, faculty members, Moore himself, and then take his own life.

He described Moore as someone he "did not like," prosecutors alleged.

Hawkins is currently being held at the Garvin County Detention Center on $1 million bail. He faces charges including shooting with intent to kill, feloniously pointing a firearm and carrying a weapon to a public assembly. A preliminary hearing conference is scheduled for May 8.

Principal Moore's Statement After Getting Shot Taking Down Oklahoma Gunman

Moore has since been released from hospital and issued a statement expressing gratitude for the support he has received. He credited his training and faith for his reaction.

"Like so many educators around the country, we prepare for these events through training and careful assessment of the threats," Moore said. "I am grateful that my instincts and training, as well as God's hand, were available to me."

Pauls Valley Police Chief Don May was less understated.

"It doesn't surprise me the actions that he took, but it is amazing, the actions that he took," May said. "There's not a doubt in my mind that he saved kids' lives."

Moore said he looks forward to returning to work as soon as he is able.
