Police have issued CCTV stills of a man they wish to speak to in connection with bank fraud offences.
On the morning of Monday, 25 July, a postman was approached by a man in Tabor Gardens, Cheam. The man showed a driving licence and stated that he lived nearby and wished to obtain his post. A number of letters were handed to the man by the postman.
Later that day, two debit cards which had been contained within the letters, were used at ATMs and over the counter at banks in Bracknell, Ascot and Milton Keynes. A total of £12,400 in cash was fraudulently obtained.
The victims - a man and a woman who live near to where the postman was stopped - spotted the unauthorised transactions at the end of the month. They had not ordered replacement debit cards.
Officers from Sutton are investigating. They have released three images of the man - described as white and possibly aged in his 50s - captured on CCTV at various banks on 25 July.
Police Sergeant Anna Smith, from Sutton, said: "It is unlikely that this was a one-off offence and, since the suspect used the cards outside of London, it is possible that he lives outside of the capital and may be committing similar offences elsewhere in the UK."
Anyone who can identify the man shown on CCTV is asked to call officers in Sutton via 101. To remain anonymous call Crimestoppers on 0800 555 111.
