Huddersfield seems to have been overrun with spiders this autumn - but we haven't seen one like this!
The grey-black beast was found underneath a pallet at Wickes in Manchester Road by two members of staff.
Supervisor Kier Brook said: "They found it and brought it in to show me. I said, that's not a British spider. It was grey and black with thick legs. It had thick legs and was smooth in appearance.
"It was bigger than a £2 coin but its thick body was very strange indeed. My colleague said he felt it gripping his fingers while he was holding it. I can't believe he picked it up!"
Kier said they weren't sure whether it was dangerous and the shop was full of customers, so reluctantly decided to get rid of it.
However, Lawrence Bee, the British Arachnological Society's press and publicity officer, said he didn't believe the spider was dangerous.
He said: "I can’t be absolutely sure of its identification – microscopic examination would be needed to confirm the identification.
"But it looks very much like Scotophaeus blackwalli – sometimes known as the mouse spider. It is not uncommon, often found in houses and completely harmless."
