They knocked on her door and one distracted her while the other walked into her front room where he found the money.

The pensioner -- who has not been named -- was left shocked but unhurt.

Sgt Bill Crittenden, of Bolton Police, said: "Utility service officials will always pre-arrange appointments and carry identification cards.

"Residents should never open their doors to anyone they are unsure of. We do not want people to be worried but everyone should always be vigilant."

The conmen are both described as white and aged in their 20s. One had blond hair.
