CHICAGO — The city of Chicago is demolishing the 200th building deemed dangerous under a program that targets vacant structures used by gangs.

In a statement Monday, Mayor Rahm Emanuel announced the demolishing of a building in the city's Roseland neighborhood on the South Side. Over the summer, the mayor launched an initiative to identify and tear down vacant buildings to stop gangs from using them to meet and conduct illegal activity.

Emanuel says the program cuts down on crime and eliminates blight in the city's neighborhoods.
