A Chicago alderman is calling for a criminal investigation after finding disturbing graffiti on a South Loop building.

The message reads "We Kill Cops".

Second Ward Alderman Bob Fioretti says he discovered the graffiti while driving the neighborhood around 12th and Michigan.

Fioretti says the city's Graffiti Busters unit will remove the spray paint.

Investigators are checking security cameras from the area to try to identify the person who tagged the building.
