Hoteliers and race-goers are being warned to keep their eyes on their bank cards as well as the finishing line during the Cheltenham Festival.
During last year's race week several hotels in the Cotswolds fell victim to a group of individuals who stole bank cards and cash from hotel rooms.
The stolen cards were used to pay for accommodation and attempts were made to withdraw cash from banks.
Investigations into the thefts are still ongoing and Gloucestershire Police have released CCTV images of those they want to speak to in relation to the thefts.
The constabulary are warning hotels and visitors to not let their credit and debit cards out of their sight and use safes in hotels.
They also advise people not to write down their PIN numbers and keep cheque books separately from cards.
Anyone who recognises the individuals in the images can contact police on 101.
