An undercover police investigation in Chicago has led to the closing of a grocery store and charges against its owner.

According to Fox 32’s undercover operation, as well as undercover police, Uptown Grocery was not only selling groceries, but also running a “flourishing” drug market. Prosecutors say Uptown’s owner, 45-year-old Ali-al-Najjar, was selling stolen goods and committing Link card fraud by pocketing some of the excess cash.

Police found more than $40,000 dollars cash in Najjar’s store and the stolen goods sold from inside the store came from retailers including Walgreens, Macy’s and J.C. Penney’s.
