ELDERLY people have again been warned not to fall prey to bogus officials.
The police advice follows an incident in Marsh when a man called at the home of an elderly woman.
Pc Dave McSweeney, of Huddersfield Police, said the man called at the home in Wellfield Bank on Monday and said he was from the YEB.
He asked her several questions about if she lived alone and whether she went out during the day.
He had no identification or clothing with official logos.
He left without entering the house.
"People should be aware that anyone visiting their home from the utility companies is likely to make a pre arranged visit.
"If they do not they will carry an identification badge, which they will be happy for householders to check," said Pc McSweeney.
"You should never let anyone into your home who you don't know, or leave them unattended at the door without locking it."
The man was white, slim and about 40, with collar-length, ginger hair.
He wore a dark suit, white shirt and black overcoat and spoke with an educated accent.
Earlier this week police warned people to be on their guard against fraudsters trying to trick their way into their homes by selling carbon monoxide detectors.
Anyone who has received similar visits should ring the police on 01484 436659.
