A man who claimed to be a plumber stole more than £1,000 from an elderly woman in a Nottinghamshire town.
The man called to the victim's house in in Stapleford to check her boiler and took money before leaving.
Officers have now issued a number of CCTV images to help with their investigation and are urging the public to be vigilant.
Investigator Martin Prentice, from Nottinghamshire Police, said: "The man knocked on the vulnerable woman's door and explained to her how he was checking a boiler at a house down the round and he needed to check her boiler too.
"She trusted him and let him into her home. He then distracted her by asking her to turn the taps on and off.
"Around £400 was taken from her purse, meanwhile more than £1,000 and a gold chain was also taken from a drawer in her bedroom.
