This month's Counter Fraud Newsletter explains how fraudsters stole more than £28 million last year due to courier scams, with most victims being in their 80s. 

Protect yourself and others from courier fraud and remember:

• Your bank and the police will never ask you to withdraw cash or purchase high value items
• Your bank may offer webchat where you may be able to get some quick advice without using the phone
• If you have vulnerable friends or family members, consider encouraging them to sign up to the Telephone Preference System and installing a call blocker to manage unsolicited calls.

The newsletter also covers what to do if a suspicious email arrives in your @nhs.net email account.
