Thieves stole £1,000 after taking a bank card from a terminally ill man as he lay on his death bed in Blackpool Victoria Hospital.
The card has been used at cash points and shops around the resort, with a 32-inch television among the items bought.
Police have now released CCTV images of two men they want to speak to following the theft, which took place between February 16 and 19.
A leather bum bag belonging to the 70-year-old patient, who died on March 4, was taken while he was receiving treatment at the hospital.
A Halifax bank card inside has since been used at cash points at Costcutter on Chapel Street, the Post Office on Ansdell Road, Asda on Cherry Tree Road and Halifax on Church Street.
It was also used on February 19 at Tesco Express on Whitegate Drive and the Tesco Extra on Clifton Drive, where the Technika 32-inch TV/DVD combi was purchased.
PC Paul Gill said: “This is a despicable offence which has caused a huge amount of distress for this man’s family.
“I would urge anybody that recognises the men pictured in the CCTV images to contact police on 101.”
