The spokesman said airport police in Nashville arrested the 16-year-old after he arrived on a flight from Los Angeles, CNN reported Friday.
"His stated intent was to hijack the airplane and commit suicide," said FBI spokesman George Bolds. "He did indicate he intended to die in Louisiana. It appears he had a ticket to Louisiana."
WSMV and WTVF, two CNN affiliates in Nashville, cited unnamed sources as saying the boy planned to crash the Southwest Airlines plane into a concert starring "Hannah Montana," the pop-star alter ego of country singer Billy Ray Cyrus' daughter, Miley Cyrus, on the Disney Channel show of the same name.
The FBI said the teenager was carrying handcuffs, duct tape and a type of rope or yarn, CNN reported.
"His plan contemplated overpowering the flight crew," Bolds said.
It was not clear Thursday night how police learned of the teenager's alleged plot.
Bolds said the teen was being held on unspecified state charges and could face federal charges as the case progresses. He is expected to appear Friday in Juvenile Court.
