Members of the public are being urged to be vigilant after a pensioner was robbed by men posing as 'water board' officials.
Two men targeted an 85-year-old woman in Grayson Green, Wellingore gaining entry to her property and stealing £20 and a top-up fuel card.
The incident took place at around 1pm on September 27, one man was white, around 30-years-old and 6ft tall with short black hair, a long thin face and a big narrow nose.
The other was between 30 and 35-years-old and had a chubby face.
Both were wearing dark sports jackets.
The men knocked on the door saying they were from “The Water Board”, that the mains supply had been contaminated and that they needed to check the supply at the address.
One man turned taps on and off in the kitchen and bathroom and talked to the woman.
While this was happening the other man searched the property and stole £20 cash and a fuel top-up card.
The men were wearing ID tags, but they did not hand them over for inspection.
Residents are being urged to never let anyone into their properties without taking their ID and closing and locking the door while making a phone call to the company in question to check they are genuine.
Police assure that if they are genuine they will have been trained to expect this and will not be offended and anyone with concerns should contact the police immediately.
Anyone who may be able to identify the offenders is asked to get in touch with Lincolnshire Police as soon as possible on 101, or by calling independent charity Crimestoppers anonymously on: 0800 555 111.
