A police spokesman said such a request could in fact be the work of scammers "who are usually operating from an overseas IP address, create a false email address in the name of an employee, and then email that employee's employer/payroll department requesting a change of bank account".
Police said there had also been instances where the scammers created a false business email account in a bid to get businesses to pay money due to suppliers into a different bank account.
Police say any requests for a change in banking details should be directly verified and such emails should not be accepted at face value.
