Police say people are posing as officers in parts of Basildon.
They’re urging people to be vigilant after fraudsters called six people asking for cash or pin numbers to aid investigations into suspicious activity on accounts.
* Your bank or the police will never call you to ask you to verify your personal details, your banking log in details, passwords or PIN by phone or offer to pick up your card by courier. They will never ask you to withdraw or transfer money. Hang up if you get a call like this.
* If you need to call your bank back to check, wait five minutes; fraudsters may stay on the line after you hang up. Ensure a dialling tone can be heard. Alternatively, use a different line altogether to call your bank.
* Don’t let a stranger take your bank cards or money from you.
