Police have warned bogus officials are operating in a Sheffield suburb after two pensioners, including a woman aged 102, were targeted.
Officers were called twice on Wednesday following incidents in Crookes, with the 102-year-old raising the alarm initially.
She told police a man called at her home and offered to clean her drains for £120, claiming the council had send him.
The elderly woman refused to agree to the work and the conman left without stealing anything.
Two hours later another pensioner was approached by two men, claiming to be farmers, who asked if they could cut her lawn at the back of her home.
Once they had finished their work the woman realised cash and jewellery had been stolen.
Detective Inspector Richard Partridge said: “Bogus officials claim to be from any public agency or utility company to gain access to people’s homes.
“The impact of this crime on the elderly and vulnerable, who are often targeted by bogus callers, can be very traumatic.
“We want everyone in Sheffield to be aware of some of the tactics they use to distract their victims, and to please report anything suspicious to us.”
Witnesses or anyone with information on bogus officials operating in Sheffield should call South Yorkshire Police on 101 quoting incident number 658 of May 15.
Crimestoppers can also be contacted anonymously on 0800 555 111.
