The Guardian (link above) doesn't report the 'failing to stop' charge:
A day after the incident, a 30-year-old man was arrested on suspicion of causing actual bodily harm under section 35 of the 1861 Offences Against the Person Act – “injuring persons by furious driving” – after he contacted police. He has since been released under investigation.
