A warning has been issued by police following a number of telephone scams across the county.

Norfolk Police received four separate reports yesterday from people who had been contacted by fraudsters pretending to be officers.

During the calls, the scammers tried to trick people into transferring large amounts of money from their bank.

One of the attempts was successful, with the victim losing £4,000.

The incidents happened across south Norfolk in Diss, Wymondham, Framingham Earl and Aplington.

Known as courier fraud, the criminal contacts a victim by telephone claiming to be a police officer, bank or from a government department, among other agencies.

A number of techniques are adopted in order to convince the victim to hand over their bank details or cash, which may then be passed on to a courier.

A spokeswoman for Norfolk Constabulary said: "Residents are reminded that your bank or the police will never ask you to withdraw, send money or purchase items.

"Officers are keen for residents to share these messages with members of their local community and also to ensure they contact family and friends, particularly elderly relatives to ensure they are aware of these scams and the warning signs."

If anyone has received a similar type of telephone call or has any information about these incidents, they are asked to contact Norfolk Police on 101 quoting Operation Radium.
