Detectives are urging people to stay vigilant following several reports of scam phone calls purporting to be from Microsoft.

In Cheshire, there have been several reports of residents receiving phone calls from fraudsters posing as workers from Microsoft.

The scammers claim to be computer security engineers and tell victims that their computers are at a security risk.

They then say that a security check needs to be performed and if the victim agrees, the scammers can then gain remote access to the computer.

This access allows fraudsters to obtain personal details about the victims including their bank account.

Detective Sergeant Chris Jacques, of the Economic Crime Unit, said: "This is a particularly heinous crime whereby scammers target the most vulnerable in society.

"This scam has seen a resurgence over the years but as time goes on, fraudsters can use more sophisticated techniques in order to persuade victims to hand over money or gain access to their computers.

"These fraudsters are often extremely convincing and pose as working for a reputable company as it gives them more credibility.

"We are doing all we can to tackle all types of fraud and I would urge anyone who believes that they have been a victim of this scam to please report it to Cheshire Constabulary and Action Fraud."

Police and Crime Commissioner for Cheshire, David Keane said: "Fraud not only leaves victims without their hard earned money, but it also has a significant emotional impact.

"As Police and Crime Commissioner, I will continue to ensure that action is taken against scammers who are so heartlessly targeting the vulnerable in Cheshire.

"I would urge residents to follow the key advice and please continue to educate and inform elderly family members about these scams."

Key advice:

• Treat all unsolicited phone calls with scepticism and never give out any personal information.
