School staff use armbar takedown on intruder

When an unknown man entered school grounds in this French school, a staff member used an armbar takedown to restrain him.

This clip displays two central issues with armbar takedowns:

  1. Control on ground – When the video begins, the staff member is controlling the arm while ignoring the man’s core, which allows the man to stand up;
  2. Injury – When he does stand up, the armbar takedown is effective but causes injury, slamming the man’s head into the ground, and a pool of blood is forming as the video ends.
