(AP) — A Missouri man who sold counterfeit goods at a store in Kansas has been sentenced to 18 months in prison.

U.S. Attorney Barry Grissom said in a news release Wednesday that 45-year-old Jehad Shalabi, of Blue Springs, Mo., pleaded guilty to one count of conspiracy to traffic in counterfeit trademark goods. He sold the merchandise at the Joe Black store in Kansas City, Kan.

Prosecutors say FBI agents working undercover bought counterfeit items at the store and agents searching the store in June 2011 seized 588 counterfeit items with trademarks including Polo Ralph Lauren, Nike and Major League Baseball.

Investigators say the counterfeit goods accounted for up 20 percent of the store’s weekly sales of $4,000 to $6,000.
