JACKSONVILLE, Fla. -- Passengers at Jacksonville International Airport said they didn't notice a big increase in the number of police officers on Wednesday. David Olsen was flying home to Dallas and said he was surprised.

"To tell you the truth, yeah, I expected more police," he said.

The discovery of two suspicious packages shut the airport down for several hours Tuesday night. Zeljko Causevic, 39, was booked into the Duval County Jail at 1:30a.m. Wednesday following an arrest by the JAX Airport Police.Authorities say Causevic was arrested at JAX Airport after he allegedlytold security screeners he had a bomb in his backpack but they onlyfound an electronic scale and batteries.

Causevic is facing charges of false report about planting a bomb orexplosive and manufacture/possess/sell/deliver or mail hoax bomb,according to the Jacksonville Sheriff's Office jail log. An arrestreport indicates he's originally from Bosnia.

A spokesperson for the Jacksonville Airport Authority said just because passengers don't see a spike in police presence doesn't mean they're not being protected.

"As far as the passengers are concerned, they may not see any ramp-up, but there are still plenty of layers of security that ensure our passengers are safe," said Debbie Jones, Community Relations Administrator for the Jacksonville Aviation Authority.

"I don't think people are going to notice any difference in the level of visibility of our officers," she said.

Jones said JAA is reviewing how Tuesday night was handled among all the agencies, and are working to improve whatever is needed.

"We're going to look at how things went and take feedback from various agencies and see what we can do," she said.
