The first officer to make physical contact attempts an armbar takedown which serves to spin the man around while remaining on his feet. Other police swarm and start grabbing at his arms and wrists. The police pull the man in all directions at the same time, which prevents escape but does not help to take him down.
One officer makes a half-hearted attempt at controlling the legs, but lets go. The man eventually is forced to lean forward, and in combination with tripping over the feet of one officer while being pulled forward in a headlock by another, he falls to the ground.
