Context is important here, you cannot equate play fighting rough and tumble with the kids to an adult male putting a smaller female into a headlock. If this was your wife, daughter or mother then I am sure this question wouldn’t even be asked. It’s assault and if there was evidenced of it we would all condemn it and rightly want the person responsible to be punished/held to account for their actions.
That said, I don‘t believe it happened and is club propaganda.
