THIS is the shocking moment a woman was savagely battered by a man during a brawl at Hyde Park's 420 event.
The fight erupted as crowds gathered for the annual cannabis smoking meet in London yesterday.
Footage shows a thug battering a woman as she lays on the ground.
She can be seen trying to push him off her as he continually punches her as the crowd just films the brawl.
One woman eventually intervenes and tries dragging the man off the woman by his coat.
Meanwhile a separate fight can be seen breaking out in the background between two girls.
