A sting in Cook County, Ill. targeting professional shoplifters in three locations has culminated in 59 arrests.

The investigation, dubbed "Operation Whoville," took place over the last month on North Michigan Avenue in Chicago, Woodfield Mall in Schaumburg and Orland Square Mall in Orland Park.

According to a Chicago CBS report, the thieves got away with large amounts of baby formula, dozens of pairs of name brand jeans and drug store items like razors. In one case, a woman was caught shoving an entire suit jacket down her pants.

Undercover agents from a countywide task force arrested 59 people who targeted malls in Schaumburg and Orland Park; and stores like WalMArt, Dominck's and The Gap.

"Operation Whoville" was a joint effort of the Cook County State's Attorney's office, countywide law enforcement agencies, retail security forces, and Homeland Security investigators.
