This is the moment an ‘asda security guard’ knocks on a man before dragging him out of the shop.
Footage shows the warden fatally hurling a devastating punch at the plant customer as he walks into an Essex store.
The guard swings a vicious right hook, knocking the lad into a pile on the floor.
He then turns around to the shopkeeper, who is wearing a matching white tracksuit, raised his fist while he appears to be unconscious.
The guard grabbed him by the hoodie before he was taken out of the shop.
Violence broke out on seeing the employees and shopkeepers.
Another video taken outside the store shows a man returning what appears to be a mobile phone that fell from under the man’s tracksuit.
Asda and Essex Police have been contacted for comment.
