McNeill says the scammers also claim to know the victim's passwords, and in some cases list actual passwords that have been used by the victim in the past, which they've obtained through previously leaked online data breaches.
Police are warning anyone who receives an email of this nature that it is a scam and to immediately delete the email.
McNeill said is also a good idea to regularly change your passwords, but it is particularly important to do so if a password listed by a scammer in the email is one that you still use.
Police want to hear from any victims.
"We ask anyone who believes they are a victim of this scam and has transferred money to contact police by phoning 105."
