Since it’s release last week, GTA IV has hit the ground running, causing waves of controversy everywhere. Now, publisher Take-Two Interactive is starting to fight back.

Take-Two Interactive has their sights set on the Chicago Transit Authority  today, suing them for the removal of ads for the game that were previously on Chicago buses and bus stops. Take-Two alleges that with the ads having been removed without explination, the CTA has violated Take-Two’s free speech and contractual rights.

In the filing Take-Two accused the CTA and its sales agent, Titan Outdoor LLC, of violating a $300,000 campaign agreement that included running GTA IV promotional advertisements on buses and at bus stops throughout the Chicago area, which were scheduled for display for six weeks between April and June.

The ads were removed in wake of a Fox News affiliate report, showing a correlation between the GTA IV ads and a surge in violent crimes within Chicago.
