This is the moment a boy racer was caught crashing at 90mph - on the dashcam of a parked police car. Officers were waiting in a layby when Lewis Box raced past with three terrified friends in his Citroen C1. Moments later he lost control and swerved from side-to-side before crashing into a vehicle from behind. Box, 20, has now been banned from driving for two years and given a 12-week suspended prison sentence after pleading guilty to dangerous driving. Remarkably, nobody in the vehicle suffered serious injury in the collision on the A4 near Chippenham, Wilts., on July 7 last year.
