A 90-year-old woman is warning people not to become victims after uncovering a prize draw scam.

The woman, from Colchester, received a letter claiming she had won one of 6,000 cash prizes, ranging from £25 to £20,000.

It said all she had to do was to ring a premium-rate number and listen out for her ID code to find out how much she had won and how to claim it.

She suspected the letter was a scam, and after proving her theory she reported it to Essex Trading Standards.
