Anti-fraud police officers have warned people to be aware of two telephone numbers which have been linked to a series of fraudulent phone calls across Yorkshire and Humberside.

The numbers are: 0113 5191578 and 0161 7682347.

They have been linked to a number of calls where a suspect claims to work for a bank and require the receiver to withdraw large amounts of cash from their account.

Arrangements will then be made by the fraudulent caller for a courier to attend the receivers address for the cash to be collected.

The receiver is often told that they are assisting with an undercover investigation or that the money is counterfeit and must be removed from their account.

Officers from the Yorkshire and Humber Regional Organised Crime Unit’s Proactive Economic Crime team are aware of the scam and are investigating.

Detective Constable Adrian Bromley of the YHROCU team said: “I would urge people to be vigilant when receiving calls out of the blue from people claiming to be their bank, particularly if you are called unexpectedly.

“We’ve identified these two telephone numbers in particular, but there are other numbers and they do frequently change.”
