Police are dealing with what they describe as a serious collision at a Waitrose after a shopper was knocked over in the car park.
The person was hit by a car just before 3pm and the area around the store in St Andrews Gardens in Colchester was cordoned off.
Waitrose said paramedics were already at the store on a less serious call out and attended to the injured person immediately before they were taken to hospital.
A spokesperson said: "We're thankful for the emergency services who responded immediately, as well as the quick actions of our Partners. Our thoughts are with the individual at this time."
The store was still open to customers but part of the car park was cordoned off though customers could still park in the remaining spaces.
Officers are asking anyone who saw what happened to get in touch.
A spokesperson for Essex Police said: "The area has been cordoned off while we investigate and we need anyone who saw what happened or has footage to come forward."
"If you have any information, CCTV, dash cam or other footage in relation to this incident, then please get in contact with us quoting incident 871 of 19 August."
