He was arrested at the airport , which was evacuated late Tuesday as a result of the scare . The suspect appeared in court Wednesday . He wore a green jumpsuit and did not speak as the judge set his bond and next court appearance -- October 23 . There was no immediate public statement by an attorney on Causevic 's behalf . According to the FBI , authorities had first feared that a larger plot was under way . `` The confluence of these three events in a short time frame suggested perhaps a larger plot was unfolding , and made necessary a significant response to evaluate the situation as a whole , '' the agency said in a statement Wednesday . The first event involved Causevic at a security checkpoint , where he indicated his bag contained a bomb . The second event unfolded when police approached a male suspect , who grew defensive and dropped a bag he was carrying . It was later determined that he had no connection to the initial threat . The man was arrested on unrelated charged , the FBI said in its statement . The third event involved a disruptive passenger on an out-bound flight . No arrests were made in that case , and it was also determined not to have anything to do with the other two incidents , the FBI said . After the airport was evacuated , some arriving flights were diverted and some passengers who were on planes that had already landed were taken to hotels . Hours later , officials issued an all-clear . `` We erred on the side of caution in terms of doing whatever 's necessary to make sure that everybody is safe , '' said Stewart .
