JACKSONVILLE, Fla. -- The FBI said three events happening at once that hinted to a bigger plot triggered the massive response and evacuation of Jacksonville International Airport Tuesday afternoon.
At 5:50 p.m., investigators say Zeljko Causevic told an agent at the Transportation Security Administration security checkpoint that he had a bomb in his bag. A police officer with JAA took him into custody for questioning and authorities evacuated the airport.
The FBI says at the same time of Causevic's questioning, Manuel Rivera became defensive as he was approached by police. The FBI says he dropped a bag he was carrying.
The JAA police department checked the bag and determined it did not contain anything of consequence. Police determined he had no connection to the initial bomb threat, but he was arrested on unrelated charges, according to the FBI.
At about the same time, JAA police received a report of an incident on an outbound flight involving a disruptive passenger. The passenger was questioned and released. The incident was not connected to the two other incidents at the airport.
The FBI said it responded as if the events were connected, but in the end, they were not.
"The confluence of these three events in a short time frame suggest perhaps a larger plot was unfolding, and made necessary a significant response to evaluate the situation as a whole," wrote FBI spokesman Jon Fletcher in a statement. "It is law enforcement's mission to ensure the safety of the traveling public and security of the airport complex."
