A conman stole cash from a Sheffield pensioner in a scam in which he told her he needed to lay cables in her garden.
He called at a house in Daisy Walk, Beighton, yesterday morning and told the OAP living there that cables needed to be laid for some neighbouring homes.
The crook was invited into OAP's house to get to the garden at the back of the property.
It is believed a second offender sneaked in behind the bogus official and searched the house.
The woman who lives there later discovered that cash had gone missing.
PC Gareth Bryant, of South Yorkshire Police, said: “We believe that the man left the front door ajar. He has then kept the woman talking in the garden before suddenly making an excuse and leaving.
“When she has gone back into the house, the woman found that a quantity of cash had been taken.
“Most people who come to your door are genuine, however it’s unfortunate that some do come with the intention of tricking their way into your home to steal from you.
“We’re continuing to investigate this incident and would like to hear anyone who saw or heard anything suspicious in the area at around that time."
The conman was white, aged in his 30s, about 5ft 7ins tall, of a medium build and spoke with a local accent.
He was wearing a yellow hi-vis jacket and a black beanie style hat. He was also carrying a clipboard.
Anyone with information should call South Yorkshire Police on 101 or Crimestoppers on 0800 555111.
