A public warning has been issued after fraudsters impersonating police officers have conned elderly residents out of four and five-figure sums.

Police Scotland has asked people living in East Dunbartonshire to stay on guard as several older people in the area have been defrauded of large amounts of money throughout August.

Initially, the criminals contact their victims via phone, convincing them they are either police or bank officials.

They then tell the victims they are concerned their bank cards have been cloned and are being used fraudulently.

Scammers then ask victims to withdraw a sum of money from a bank, post office or currency exchange, which is then collected from their homes by fake non-uniformed police or bank staff impersonators.

Police officers or bank workers never contact the public to ask them to transfer or withdraw money.

Police urged anyone who is unsure if a call, text or email is genuine to contact the number on the back of their bank card.

The force issued the message: “This is a scam – hang up the phone – do not engage – do not withdraw cash to provide to a stranger.”

They also said people should never contact any phone numbers given to them by a possible scammer.

Police are now on the hunt to find those responsible for the recent fraud in the area.

Local area commander for East Dunbartonshire, chief inspector Aidan Higgins, said: “I would like to reassure everyone that extensive inquiries are being carried out by a team of specialist officers to identify those responsible.

“This type of crime occurred in the area earlier in the year and a man was arrested and charged.

“Unfortunately, we are continuing to see this method being used to deceive and defraud members of our East Dunbartonshire community.

“It is important that everyone is aware of this scam and to be vigilant of such phone calls. Do not be fooled, even if the scammer uses your name and gives a plausible story. I would ask anyone with elderly relatives or neighbours to make them aware of this fraud as soon as possible.”

The chief inspector added: “These callous criminals prey on vulnerable people in our communities.

“They go to great lengths to appear legitimate, including having your personal details.

“The victims are persuaded to believe that they are assisting with a police investigation and are extremely upset and distressed when they find out they have been the victim of fraud.

“If you receive a call of this nature, do not engage with the caller and hang up. It is a scam. If you’re unsure, take a few moments to think. If you can, note the caller’s telephone number, hang up and contact police on 101.”
