A cyclist says he is lucky to be alive after being knocked off his bike by a car whose driver is believed to have tweeted about the crash.
Toby Hockley, from Norwich, was near the end of a 100-mile cycling event when he was hit by a vehicle near Snetterton in Norfolk.
He says he ended up in a hedge and the driver failed to stop.
Police are investigating the tweet.
