A PROMOTIONS card was used to buy £50 worth of clothing illegally.
The real owner had dropped her Sainsbury's Nectar car in the petrol station at the Tollgate store.
It was picked up and used to buy clothes in the store.
Officers are hoping someone will be able to identify the woman in the CCTV images who is wanted for questioning.
The card was used on January 14 with details released today.
Anyone with information call Colchester police on 101.
