Police are warning people in South Holland to be vigilant after two suspected cases of bogus council officials visiting homes in the area.
Both incidents happened on Tuesday in Whaplode and Holbeach St Johns where two men wearing in high visibility jackets claimed to be from South Holland District Council offering free loft insulation.
South Holland Community Policing Inspector Jim Tyner said: “These types of offences are despicable as the offenders prey on the elderly and vulnerable in our society.
“The men tried to trick their way into the homes by pretending to be council officials but thankfully, they were foiled by quick-witted residents.”
“We are asking people to be good neighbours by keeping an eye on elderly or vulnerable neighbours.
“If you are suspicious, record car registration numbers as distraction burglars are trying to trick their way into people’s homes to steal money and valuables while the householder’s attention is elsewhere.
“Most callers are genuine and mean you no harm, but bogus callers can often seem very plausible and will try to fool you.”
Anyone with information should call 101.
