Chicago Police confirmed they are responding to a call of an "incident" at the Willis Tower in Chicago's Loop Wednesday afternoon.
When asked about the activity at the skyscraper, located at 233 S. Wacker Dr., Chicago Police Supt. David Brown said during a press conference Wednesday that officers found any reports of an active shooter to be unfounded.
"Not accurate reports of any kind of active shooter -- debunked it almost immediately. Taking good care and ensuring that there’s no other activity currently," Brown said.
Brown added that in light of the county's mass shootings, police "are taking every precaution," following all normal protocols until able to debunk a report.
