MIAMI -- Several people have been indicted on accusations that they sold counterfeit items at a South Florida flea market.

At a news conference, U.S. Attorney Alex Acosta held up counterfeit items that could pose a risk to South Florida residents. Five Miami residents are accused of selling the items.

"A cord identical to this was plugged into a space heater and a 100-watt lamp and after some time created sparks. If used on a Christmas tree or for decoration, this could create a fire hazard to your home," Acosta said.

Investigators confiscated trailers full of fake goods, such as designer purses, fake clothing, jewelry and more, sold at the Opa-Locka Flea Market and area warehouses.

"This isn't a victimless crime. The trafficking of counterfeit goods costs U.S. citizens jobs, costs tax revenue and affects the reputations of companies big and small," said Anthony Mangione, of Immigration and Customs Enforcement.

Perhaps the most dangerous items found by investigators were imitation Glock pistols.

"You'll see when you open up the package the orange blaze comes off, leaving just the toy gun -- a gun that has a working fire mechanism," Acosta said.

"Think of the police officer in the dead of night, working in the rain, and he sees that on someone. Think about what his reaction could be. That's a tragedy in the making," Mangione said.

Investigators said they seized 2,500 of the counterfeit guns.

Officials said they need the public's help to crack down on the growing problem. If you have any information about fake goods being sold in South Florida, you can call the federal counterfeit hotline at 1-866-DHS-2-ICE.
