Police have released CCTV images of a person they'd like to speak to in connection with the use of a stolen credit card - taken from the victim's car.
Officers are warning motorists to be extra vigilant: ensuring cars are locked and valuable items, such as bank and credit cards, are removed.
The warning comes after the card was stolen from a car in Gooch Street, and then used for several contactless payments totalling £110, including at the Applegreen Petrol Station, Swindon, between 3am and 4.15am on 18 October.
PC Steve Yeates, from Swindon Community Policing Team, said: "Motorists should always be extremely careful with any valuable items. Unfortunately, there are people who will look to take advantage of that one time a purse is left on show or a car door may be accidentally left unlocked.
"Be vigilant: remove valuables from cars when you are not in them and double check you have locked your car before going to bed."
The person, believed to be female, has dyed red hair and was wearing a distinctive grey Nike hooded top, black leggings and carrying a sand-coloured holdall.
Anyone with information on this person's identity should call 101 and quote crime reference 54190103889.
