CCTV footage has captured the moment Kirk Moore, principal of Pauls Valley High School in Oklahoma, charged at and tackled a former student who opened fire inside the school on 7 April. The suspected gunman, Victor Hawkins, was subdued with the help of a staff member who disarmed him, and was arrested at the scene. Moore, who sustained a gunshot wound to the leg, has since been discharged from hospital, while Hawkins faces multiple charges including shooting with intent to kill and unlawful carrying of a firearm.
