A BOGUS official targeted an elderly woman at a house in Pontefract on Monday.
Police are appealing for information after a man entered an unlocked property on Love Lane between 2.30pm and 3pm and told the 73-year-old occupant there was a problem with the water and drains.
When the man left, the woman noticed £40 was missing.
The suspect is described as a white male in his mid 20s, with stubble, dark brown thick short hair, with a gaunt face, skinny build, wearing a cream or white t-shirt with black writing and jeans.
Witnesses or anyone with information should call police on 0845 6060606 or Crimestoppers, in confidence, on 0800 555111.
