Fake car accessories worth more than £10,000 have been seized by officers from Lancashire County Council Trading Standards service following raids on three addresses in Leyland and Chorley.
Trading standards officers from Lancashire County Council and the police served warrants last Monday on two houses and a factory suspected of being used in an operation to sell counterfeits over the internet.
The goods seized included floor mats and embroidered badges, which had been branded with the logos of manufacturers including Renault, Mini, Vauxhall, and BMW.
A number of business names were reportedly found to link to one factory.
Complaints from customers about the quality of the goods purchased were also found.
Investigations are continuing while officers consider charges under trademarks legislation for the organisers, who were trading on the internet including on an auction website.
Those involved are suspected to have earned thousands of pounds from selling the fakes as genuine items
Lancashire County Council declined to reveal the locations of the raids.
In the last month, Lancashire trading standards has received 80 complaints about counterfeit items.
