Last month, footage emerged of a car passenger leaning out of the window of a moving vehicle to push a woman off her bike in a country lane.
Footage of the incident was taken by someone in the car and posted on Twitter and YouTube.
The video shows the car travelling along a country road, before the driver pulls slightly out and slows as the vehicle approaches the woman.
A hooded passenger then leans out of the back window and pushes the woman, who can be heard shouting as she falls into a hedge.
