Officers uncovered thousands of pounds worth of fake designer trainers, clothes and bedding in an industrial container.
Lincolnshire Police and Trading Standards uncovered the goods at an industrial unit on Burgh Road and Fantasy Island in Skegness.
The haul of counterfeit Adidas, Nike, Timberland, Ugg and Balenciagas filled a 20 feet freight container.
Andy Wright, principal Trading Standards officer at Lincolnshire County Council, said: “We know that these types of counterfeit goods are sold at prices close to that of the genuine product, but nowhere near the quality.
“Many people see the sellers as Del Boy and Rodney type characters. In fact nothing could be further from the truth. Serious Organised Crime Groups are involved in trading counterfeit goods.
“These groups will often be involved in people trafficking, modern day slavery, drug trafficking and other serious offences. Serious organised crime gangs will exploit every avenue in human misery to make money.”
Anyone who can help Trading Standards with their investigation is being urged to call 08454 04 05 06 anonymously.
