SHOP staff foiled a man trying to use fake £20 notes in Marsh.
The area has a Shopwatch scheme, which means most of the traders on Westbourne Road are in constant contact with one another if any crime happens there.
Alison Rayner, owner of gift shop Don't Forget, said: "Everyone knew straight away when the man tried to use the fake £20 notes.
"He didn't manage to spend any."
One of the shops the man targeted late on Thursday morning was Westbourne News. But the man was thwarted by co-owner Doreen Peel and her ultra-violet machine, which immediately shows up fake notes.
She said: "The man came in, asked for 10 cigarettes and then tried to pay with a £20 note.
"It just did not feel right and when I put it under the ultra-violet light the £20 figure did not light up - which it does with a genuine one."
When she told the man the note was dodgy, he said he had only just got it and quickly left the shop.
He is white, in his early 40s, short and squat.
He wore fawn shorts, a fawn shirt and trainers.
Sgt Tim O'Sullivan, of Huddersfield police, said: "We have not had reports of counterfeit £20 notes in the Huddersfield area for a while.
"But we would urge shops to let us know as and when they come across them."
