We were recently contacted by a former member of the Royal Observer Corps - an elderly gentleman - who had fallen victim to fraudsters who had managed to steal his account details by pretending to be from his bank.

We were able to help this gentleman get his affairs in order, but the best defence is not to be caught out in the first place. Take a look at this excellent advice page from Age UK:
