Detectives in Westminster are appealing for help to identify a fraudster who conned a victim in his 90s out of a five-figure sum.
CCTV footage and a still image released by police show a man who police want to speak to in connection with the incident. He is described by the victim as being of Middle Eastern appearance and in his late twenties.
Detective Constable James Kapp, of Westminster CID, said: "The suspect targeted an elderly man by calling him on December 5, and convincing him that he worked for the 'Barclays Fraud Squad'.
"Meetings were arranged in the St John's Wood area on December 5 and again on December 6, and the victim handed over around £10,000 to the suspect.
"The victim soon realised that he had been the victim of a fraud, but by then it was too late."
Anyone who recognises the male pictured or has information concerning this incident is asked to call police via 101 quoting reference number 4103/090218.
