Elderly and vulnerable residents in Lowdham are being warned to be vigilant after a spate of distraction burglaries in the area.
There have been five distraction burglaries across Nottinghamshire between October 14 and 18 – including Lowdham.
Previously, there had been only one since the start of September.
Elderly residents in Ollerton, Forest Town, Mansfield and Cotgrave were also targeted.
On each occasion, burglars claimed to be doing official work in the area before they or an accomplice steal from the homes.
The offenders claim to be from the council or water board, doing gardening or guttering work, or even checking homes following a gas explosion.
Detective Inspector Pam Dowson, of Nottinghamshire Police, said: “Our message is simple – if you are not expecting someone coming to your home, don’t answer the door. Official callers will always make an appointment in advance.
“Unfortunately these unscrupulous people tend to prey on the most vulnerable people.”
Anyone who sees anything suspicious should call Nottinghamshire Police on 101.
