CCTV footage released by West Midlands Police shows the moment a woman and child were hit by a speeding car that failed to stop.
The footage shows the pair crossing King William Street, Coventry, at 7:30pm on 7 December 2012, when a black car overtakes another and knocks the pedestrians flying.
The 42-year old victim – a driving instructor, and her three-year old nephew, were luckily left with only minor injuries.
Police are now tracing the black Audi that ploughed into the pair. An eyewitness said the registration plate began with EN57 but couldn't remember the end characters.
