While United did not reveal the specific nature of the security concern, air traffic control audio from Dane County Regional Airport reviewed by WISN revealed that the passenger made "multiple attempts to breach the cockpit."

"I do not believe they ever cuffed him, but they were able to finally get control of him after multiple attempts to try to breach the cockpit," a crew member says on air traffic control audio. 

"I believe at this point he is seated in a seat and flanked with law enforcement officers on either side."
