A warning has been issued by police regarding a telephone scam.

Two people in Norwich received a phone call from a man claiming to be a detective today (April 5).

The caller told them that their bank cards had been cloned and money had been taken, in an attempt to gain their banking information. Both attempts were unsuccessful.

Courier Fraud happens when a fraudster contacts a victim by telephone claiming to be a police officer, bank or from a government department, among other agencies.

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

Banks and the police will never ask someone to withdraw money or purchase items.

If someone calls claiming to be a police officer, ask for their identification number and police force. Hang up and call 101 using a different phone.

If you can't use a different phone, wait at least five minutes before calling back.

Ensure you can hear a dialling tone before calling police.

If anyone has received a similar type of telephone call they should contact police on 101 quoting ‘Operation Radium’.
