"One victim told me she felt like she was under a spell and just doing what she thought was right.
"She was brought up trusting people and just wanted to help with their investigation."
The detective said this week is Fraud Awareness Week, and offending of this nature clearly highlights the lengths scammers will go to and the tactics they use.
Police urge people to have conversations with vulnerable or elderly family members, to help ensure they are aware of the tactics often used by scammers and don't become victims of this offending.
"The police message about this type of offending is simple – do not engage with anyone on the phone. Police and banking organisations will never ask for this type of assistance over the phone," says Detective Sergeant Leathem.
"If you think you are being scammed just hang up immediately – you're not going to offend anyone – and report the matter to your bank and police.
"If you are in doubt as to the legitimacy of a caller's identity, ask if you can call them back, or just hang up and never open any links that are emailed to you by the scammer.
"One click is all it takes for these offenders to have access to your information.
"If you have unfortunately opened a link that has installed remote access to your computer, make sure the device is shut down, or disconnected from the internet and seek assistance to ensure it is safely removed."
In the case of these recent incidents, inquiries are ongoing.
