ROGUE traders are swindling cash out of Huddersfield people by pretending to etch security codes on cars.
A group of men have been approaching people in Crosland Moor and offering to etch security codes on car lights and windows for £19.99.
But they do not etch the glass; they simply mark it with an ultra-violet pen.
These pens - which can be obtained free from the police - are used to mark household goods such as TVs.
If goods are stolen and recovered, police can shine a UV light on the writing and see who the item belongs to.
The UV ink can come off certain items - like cars - if they are washed.
David Firth, who lives on William Street in Crosland Moor, said his wife was approached by the rogue traders on Tuesday.
He said: "They say the pen is permanent but it washes off.
"My wife did not pay for it done, but a lady up the road had it done.
"Some people are gullible and these people sound plausible," he added.
Mr Firth said the men had claimed to be from Morley.
Paul Smith, a principal officer at West Yorkshire Trading Standards, said: "Until now the problem was not known to us. But Huddersfield police have been informed. Also, I would like to thank the residents for the information.
"You have to be careful who you deal with door-to-door.
"There are people out there who prey on the most vulnerable people.
"I would have thought UV ink would wash off after a while on a car.
"If people want etching done, I would recommend phoning up their local police crime prevention officer to ask for advice on car security,
"Secondly, I would say always think twice about buying any service on the doorstep."
