"London mayor Boris Johnson has rescued a woman who was being attacked by an armed group of young girls, chasing them down the road on his bicycle."
Go to the link for more information.
Well I find this whole thing quite funny... still perhaps this is all one big conspiracy :O perhaps he payed them to attack her so he could come to the rescue...
I'll leave you to decide, along side the image of Boris chasing a gang of hooded girls down the road with an iron bar in hand.
