Police are warning residents in the Walnut Place area of Lincoln to be vigilant after an elderly lady was scammed out of cash.
An unknown man knocked at the window of her flat at around 9am on Monday, July 17 and alleged he was from Anglian Water.
He was described as a small, slim white man in his 40s, wearing a bright yellow vest and blue baseball cap, and carrying a small set of aluminium ladders.
He went on to say she owed him money for work he had to do, and escorted her to a cash point, walking along Tentercroft Street.
Police say the man supported her as they walked, and was carrying a small step ladder.
After handing over some money, the man is said to have quickly fled, still carrying a stepladder. The lady was unharmed.
