Lincolnshire Police are warning residents to be wary of letting individuals claiming to be representatives from organisations into their homes.
On March 4 between 5.30 and 6pm, a smartly-dressed male gained access to a home in the Hartsholme area of the city under false pretence.
He claimed to be a water board contractor trying to turn off water supplies due to contamination in the water.
The male has been described as around 5’7″ and in his mid forties, dressed in a shirt and tie.
If someone claims to be an organisation representative, police advise residents to always ask to see identification before letting them into a home.
If you have seen or been contacted by this man or have had a similar incident happen, contact Lincolnshire Police on 0300 111 0300, quoting incident 416 of March 4.
