FAKE designer goods worth £800,000 have been seized in Kirklees.
Trading standards officials said a raid in Ravensthorpe had uncovered an operation intending to sell poor-quality goods over the internet.
Two people were arrested as the haul of clothes, shoes and accessories was found in a warehouse.
A further three people were arrested in an associated drugs raid on the premises.
Officials said the counterfeit products
had labels with the names of Adidas, Rockport , Gucci, Versace, Armani, Stone Island and other companies.
Graham Hebblethwaite, West Yorkshire's Chief Trading Standards Officer, said: "Internet sales of counterfeit goods are becoming a huge problem as electronic shopping becomes one of today's growth industries.
"As result many illegal sales are going undetected.
"Anyone who has bought or suspects they have bought counterfeit goods should report the seller to Trading Standards."
Police said rogue traders who dealt in fake goods would not be tolerated.
Det Insp Andy Parr, of Kirklees CID, said: "We are determined to crack down on this illegal trade.
"Counterfeit goods cost the clothing industry, legitimate businesses and retailers an enormous amount in lost revenue.
"What's more, anyone who buys such goods also risks obtaining sub-standard items - with no way of recovering their loss."
