It seems there could be another scam doing the rounds in Burton, Uttoxeter and South Derbyshire, as there have been reports of people getting calls from somebody claiming to be from the Inland Revenue.
Gloria Cooper, 79, received a phone call from someone claiming to be from the Inland Revenue.
She claims the caller said she owed money, and she had been sent warning letters about it, but she says no letters have been delivered to her.
Mrs Cooper, who lives in Ordish Court, Burton, said: "I think it must have been a scam. I worked in the tax office for years, so I have a bit of a clue about what goes on there. I know they don't just ring people saying they owe money without any warning.
"They were asking for my National Insurance number, which I don't even know. I couldn't give it to them because I didn't have it myself!"
After the phone call, Mrs Cooper spoke to a neighbour, who also claimed to have been called by the scammers.
She said: "He also had a call. They asked him for his National Insurance number, and he kept telling them that he didn't have it. They eventually put the phone down on him, so he knew it must have been a scam."
Anyone who receives a call from someone claiming to be from the Inland Revenue is warned not to give away any personal details and instead contact Action Fraud on 0300 123 2040.
