Reports of an active shooter at Willis Tower on Wednesday afternoon were unfounded, police officials said.

The call of the threat came in at 3:45 p.m., Chicago police said. The report was for an active shooter targeting the 50th floor, but Chicago Police Supt. David Brown said in an unrelated news conference the reports were quickly “debunked.”
