Video: White van man attacks cyclist

It's our equivalent of the Russian dash cam: the eternal struggle between motorists and cyclists has seen many riders don helmet cameras in a bid to document the abuse they suffer on the roads.

This latest footage comes from the streets of Birmingham, where a cyclist is chased down the road after seemingly upsetting a white van driver. After narrowly avoiding a door-based clothesline attempt, the biker is eventually cornered, dragged off his bike and left to fend off a flurry of blows.
