A Spirit Airlines flight set to depart New York's LaGuardia Airport at 10:45a ET for Fort Lauderdale, Fla. was held after a flight attendant heard a passenger on board say something that sounded threatening. The plane was then pushed over to an unused part of the runway and all baggage was taken off the flight and re-screened. The passengers reportedly stayed on board for this process, and if all checks out after authorities investigate, the flight will once again get underway.

Stay tuned for more details.
