They were caught on camera while using the cash cards of a vulnerable pensioner that had been stolen from her home in a burglary in Brighton.
Burglars visited the victim’s home in Sandown Road, Brighton, on 17 or 18 November, broke into a key safe outside the property and got into her flat.
They took the 88-year-old’s cash card and then withdrew a total of £2,000 at machines at Asda in Hollingbury on 18 November, in Basildon and Romford in Essex on 19 November and at an HSBC machine in Ditchling Road, Brighton, on 20, 21, 22 and 23 November.
Sussex Police launched Operation Magpie to tackle burglary across the county.
Detective Constable Jane Kemp said: “The victim is a vulnerable elderly lady who suffers from Alzheimer’s and we are determined to find those responsible.
“Each of the three people we want to speak to appears to be white and aged 17 to 21.
“The first man had dark hair and was wearing a grey top, black trousers and white trainers. The second man had dark hair and was wearing a half blue and black shellsuit-type top, dark trousers and dark trainers.
“The woman was chubby with long dark hair. She has a grey tracksuit top on with a word written on the front and grey tracksuit trousers.
“If you know who any of these people are or where they could be, please contact us.”
