Detectives have issued an urgent warning after a recent spate of fraudulent calls from scammers claiming to be police and targeting the vulnerable and elderly.

The force has seen a number of reports of fraud where organised crime groups (OCGs) call victims and purport to be from the police.

Typically on answering the call, an automated message is played, telling victims that a warrant is out for their arrest or that a loved one has been apprehended.

The scammer then asks the victim to press a number connecting them with a member of the OCG who then confirms the victim's details and demands the transfer of money from their bank to clear their name or free their loved one.

Officers are now urging others to stay vigilant and alert vulnerable family members or neighbours to this scam.

Detective Sergeant Chris Jacques from Cheshire Constabulary's Economic Crime Unit said: "Fraudsters are extremely convincing and can be very threatening especially towards the vulnerable.

"Police officers will never ask you to transfer money or provide personal details over the phone to 'clear your name' or to free a loved one.

"It is concerning that we are seeing a few reports of this and banks have thankfully stepped in to protect customers from falling foul to these scammers.

"Anyone who is receiving calls asking for money to be transferred by scammers should call 101 or report it to Action Fraud immediately."

Anyone who believes they have been contacted fraudulently or have been a victim of fraud should call Cheshire Police on 101 and Action Fraud on 0300 123 2040.
