This couple is wanted in connection with stealing thousands of pounds from an elderly woman in Crawley town centre, police said.
A spokesman for Sussex Police said thieves stole the 86-year-old victim’s purse in Savers, Queens Square, on April 2.
A police spokesman said the woman was followed into a bank by a man and a woman.
Officers believed they watched her enter her PIN and then followed her across town without her knowledge.
The spokesman said she was approached in Savers, Queens Square, and asked her for help choosing items in a shop in order to distract her and the man stole her purse.
The victim did not notice until she went to pay for her shopping and found her purse had gone.
It contained bank cards, a £20 note and some stamps.
She discovered while cancelling her card £2,000 had been taken and another £2,500 worth of products from Argos had attempted to have been bought, some of which were authorised.
PC Louise Giles said: “We have some very clear CCTV images of the people we believe to be involved in this theft.
“This was a heartless theft from an elderly lady they could tell was vulnerable and it has left her faith in people badly shaken.
“I am appealing to anyone who knows who these people are to get in touch. Contact us on firstname.lastname@example.org quoting serial 714 of 02/04 or contact the independent charity Crimestoppers anonymously on 0800 555 111.”
