CONMEN fleeced an elderly woman of £3,000 of savings.
The victim, of Cedar Drive, Chichester, was telephoned by a man who convinced her he worked for her bank, and told her she must hand over her bank card.
A courier was sent and she handed the card over.
The cash was taken from her account.
It happened on January 14 and soon afterwards a 90-year-old woman in the city was targeted but her carer turned the courier away.
Police would like to speak to the man pictured on CCTV.
Det Con Amanda Gamlin said: ‘Under no circumstances would the police or your bank request your PIN number over the telephone or arrange collection of your bank cards from your home address.
‘Never give out your bank details or hand over your bank cards to someone who has contacted you in this way.
‘If you have elderly or vulnerable friends or neighbours please make them aware of this scam as well so that they do not become a victim.’
Contact Sussex Police on 101 with information.
