A shocking video shows a hit and run motorist knocking down a cyclist - and then turning off their lights as they drive away. Police released a 25-second CCTV clip of the 4.30am incident in a bid to catch the runaway driver. It shows the moment a Vauxhall Corsa-type car pulls out of a junction in Swindon, Wilts., and hits a male cyclist pedalling past. The man is knocked off his bike and tumbles to the ground before getting to his feet and does not appear to be seriously hurt.
