Police are asking people to be vigilant after four people were stolen from while in their own homes during distraction burglaries.
Officers say the thefts have been reported across Nottinghamshire and involve “elderly and vulnerable” people.
In one incident, an 84-year-old woman, who suffers from dementia, was targeted by a man and a woman who offered to jet wash a back yard in Bircotes on Wednesday (June 7) at around 6.20pm. They got away with £100.
The pair are described as white and in their mid fifties. The woman was of a large build and they were thought to be driving a grey Vauxhall van.
Anyone who recognises the description or has any information that could help, is asked to contact officers on 101 quoting incident 708 of June 7.
There have been at least three other incidents in Nottinghamshire over the past week.
On Thursday, June 1, a 91-year-old woman in Mason Court, Bestwood, was targeted by two men claiming to be carrying out work on a water leak.
On Saturday, June 3, an 88-year-old woman had jewellery and money taken from her bedroom in Welton Gardens, Bulwell, by two men offering to clear her gutter.
On Monday, June 5, an 86-year-old man let two men into his property under the pretence of fixing his guttering. Police did not say where this happened, but asked people across the county to be wary of doorstep callers and keep an eye out for older neighbours and relatives.
A force spokesman said: “Officers are following up a number of leads but are urging people to stay vigilant when answering the door to unknown callers and are asking the public to look out for their elderly neighbours.
“If you see someone approaching a property and are suspicious about it, please report this to us on 101 and where possible, note any descriptive details.”
