When you are holding your attacker on the ground, they may start to escape, so it is useful to be able to move into another hold down to keep them pinned on the ground.
Starting in the first hold down as shown on the White Belt.
Take your attackers right arm from under your left arm-pit.
Take your right arm from around your attackers neck and place it on the ground. Now put your attackers right arm across their neck as shown.
Take your left leg over your right and finish in the North-South position on your knees. Both hands should be holding your attackers belt to keep their hips pinned to the ground. Ensure that you always have your weight on top of your attacker. You should be able to control your attacker well from this position.
