JACKSONVILLE — A trucking company worker was arrested on charges of making a false bomb threat that prompted a five-hour evacuation at Jacksonville International Airport in Florida this week.

Zeljko Causevic, 39, of Jacksonville, walked up to a Transportation Security Administration agent on the evening of Tuesday, Sept. 30, and pointed to his camouflage backpack and said, “I got a bomb in here,” the arrest report said.

Causevic.

He carried a luggage scale, batteries and cell phone in the backpack and had a remote-control device that he referred to as a “detonator.”

Causevic then told the agent it was “supposed to be a bomb, but it’s not.”

The airport was evacuated, while a bomb squad checked out his backpack and examined a second suspicious package that was found in a parking lot and determined to be harmless.

Causevic was jailed on charges of making a false report about a bomb and the manufacture or possession of a hoax bomb. He is a U.S. citizen, born in Bosnia Herzegovina and employed by the Swift Trucking Co.

The airport reopened late Tuesday night. Flights were arriving on schedule on Wednesday morning, but more than 20 outgoing flights were canceled.
