A Florida professor was arrested and removed from a plane Monday after his fellow passengers alerted crew members they thought he had a suspicious package in the overhead compartment.

That "suspicious package" turned out to be keys, a bagel with cream cheese and a hat.

When confronted by the US Airways crew about his "suspicious package," Milatovic got on his cell phone. The crew asked him to hang it up and sit down. When he refused, he was cuffed.

Milatovic was also charged with interfering with the operation of an aircraft.
