A video has emerged this evening on social media of a vehicle believed to be involved in a hit-and-run outside a supermarket that left a person seriously injured.

A hired car was driven at shoppers at Tesco Superstore in Rickmansworth at around 2pm on Sunday.

A clip on Facebook, uploaded this evening, and already shared tens of thousands of times, shows angry and shocked shoppers screaming for the people inside a blue Citroen C3 to get out as they attempt to flee the car park.

Watford Observer:

The car is attacked with bars and trolleys and can be seen moving uncontrollably as the driver searches for an escape route, while a passenger can be seen flying forwards and backwards.

People try in vain to stop the vehicle before it smashes into a car knocking its own wing mirror leaving it hanging.

Passers-by continue to ram the car with trolleys screaming ‘Get out of the car’ before others respond shouting ‘just leave them’, after they manage to open the driver's door.

It goes calm for around ten seconds before the driver revs the engine and slams full-pelt into a parked car. It then forces its way through a gap knocking another car out of the way.

The back window already smashed, the vehicle is struck again before they eventually spot a clear route out and can be seen hurtling away to the sound of car horns blaring in the background.

The vehicle eventually escapes

It is believed the incident happened after people were challenged by security staff in Tesco after an attempted theft of alcohol.

During the getaway, "several people" were stuck by the Citroen.

Yesterday, before the video was published, police issued a desperate hunt to find a blue Citroen C3 with the registration plate KW18 HGK. 

No update has since been given on the investigation.

It is unconfirmed whether people had already been hit before this video was taken.

Anyone with any information is asked to contact police on 101 quoting ISR 397 of December 23.
