Police have warned the public to be on their guard following reports of a new postal scam operating across Norfolk.
Officers say the letter claims to be from the Korea Development bank of Japan.
It states that the recipient has a similar name to someone who left a large amount of unclaimed money and requested access to their bank deals to complete a so-called “exchange” between them.
A Norfolk Police spokesman said: “Even though the banking institute referred to in the letter is genuine, the letter itself is believed to done by a person who is not genuine as such it is believed to be a scam.
“Never respond to these letters and never give out bank details or money.”
Anyone who receives a letter of this kind is asked to either contact Norfolk Police on the non-emergency 101 number.
Information can also be passed to Action Fraud, the UK’s national fraud and internet crime reporting centre, by phoning 0300 1232040.
