Teacher Keanon Lowe was able to prevent a worst-case scenario at a US high school, risking his life for colleagues and other students in a moment captured on camera.

A student armed with a shotgun entered the building of his US high school. Instead of running away, sports teacher Keanon Lowe approaches the young man and embraces him. Soon after another colleague calmly disarms the student and takes his gun.

Although at first seen as a potential school shooting, the student was suicidal and did not want to harm his fellow students. There was only one bullet in the gun.
