Rickmansworth Tesco: Worker broke back in 'hit and run'Follow @WatfordLondon
A supermarket worker broke her back when a car drove into her and others outside the store, her colleague said.
One person was taken to Watford General Hospital after sustaining a serious injury. Another person sustained slight injuries and also received hospital treatment.

A fundraising page set up to support the victim has already raised nearly four times its target.
The video shows the blue car being rammed by shoppers with trolleys and crashing into other vehicles nearby before it manages to drive away from the store car park.
Police are still trying to find the vehicle and its occupants and confirmed no-one had been arrested.
Julia Matthews, a colleague and friend of the injured woman, set up the fundraising page.
She said: "She shouldn't have had this happen to her ever, but especially not just before Christmas.
"She should be at home with her family, with her partner and her child enjoying the holiday."
Ms Matthews added she hoped the money would help her colleague to enjoy Christmas when she was allowed to go back home.
"I've created this for all those who have asked for a way to help, to help bring some positivity and love into her life when it has been shattered by selfish criminals," she added.
More than £800 had been pledged by 14:00 on Boxing Day.
Officers said the driver and a passenger had been involved in an "incident" inside the store in Harefield Road moments beforehand.
A person was challenged by security staff after allegedly attempting to steal alcohol.
Police said they were examining CCTV from the car park and store after a car was "in collision with several people outside the Tesco store".
A spokesman for Tesco declined to comment about the incident but said they would be supporting the police investigation.
Anyone who witnessed the incident and has yet to speak with police, or saw the car before or after the incident, should contact PC David Johnson from the Road Policing Unit via the non-emergency number 101, quoting ISR 397 of December 23.
