Chicago police say they made several arrests as they shut down an open air drug market on the city's South Side. Investigators set up a sting they called "Operation Crown Vetch" on several street corners in the South Shore neighborhood.

Officers videotaped people buying and selling drugs.

Prosecutors charged 11 people in the investigation. Police say they all are members of the same street gang.
