CHESHIRE Police are warning people across the county to be on their guard following reports of suspicious phone calls.

The caller claims to be an officer from the Metropolitan Police, who is investigating an incident in London and asks the person to call back on 999.

The motivation for the calls is unclear but police believe it is an attempt to gain access to personal information.

Cheshire Police advice is to not respond to the calls and to note that a police officer would never ask you to call back on 999.

If in doubt ask for the officer′s name, collar number and station and then hang up.

Using a different phone, as the caller may still be linked to yours, call 101 to check the identity of the officer.
