THIEVES who have struck all over the country have been to Huddersfield.
The conmen turn up at the home of elderly people and say they are doing crime prevention work.
But while they are drilling through doors to make space for spyholes or intercoms, one searches the house and steals cash and valuables.
Two men called at the home of a 76-year-old woman on Lowerhouses Lane, Lowerhouses, at 11.30am last Friday.
One said he was there to fit an intercom and immediately started to drill a hole in the wooden door frame.
She said she had no money and the men then realised they had been seen by the victim's grand-daughter, who lives nearby.
They drove off in a blue car, number P226 CVE.
Sgt Tim O'Sullivan, of Huddersfield police, said: "The car has been spotted all over the country.
"It has been linked to a series of crimes where elderly victims have been targeted."
One of the men is white, in his 40s or 50s, 6ft tall and heavily built.
He wore glasses, a yellow shirt and tie and carried a clipboard.
His accomplice is also white, with greying hair. He carried a toolbox.
