Fraudsters target Tesco and Morrisons customers with coronavirus scams

But the tricksters have made a few mistakes that should be a red flag to potential victims.

Firstly, the email claims to be from Tesco.com which is not a legitimate website, and secondly it is signed from the "Tesc0 team".

Action Fraud warns: "Don’t click on the links or attachments in suspicious emails and never respond to messages that ask for your personal or financial details."

Most of the emails sent by scammers relating to coronavirus are phishing messages.

It means that they send them out at random in the hope that you might be fooled into handing over the information that they're after.

Commander Karen Baxter from City of London police said: "It is extremely important that if you receive an email or text out of the blue that you are not expecting, you don’t click on any links or attachments.

"Instead, visit the official GOV.UK website by typing it directly into your web browser so you can ensure the information you are seeing is genuine."

The Sun Online revealed how one phishing scam saw crooks send e-mails claiming to be from the government offering recipients tax refunds to cope with the coronavirus crisis.

Several fake "diagnosis" scams and hoaxes are doing the rounds online.

Instagram has already banned rogue coronavirus filters that claim to "diagnose" your condition.

Fraudsters have also impersonated the World Health Organization and urges victims to open a document that supposedly contains information about how to stay safe.
