A security screener at Los Angeles International Airport has been arrested after quitting his job and making threats that led officials to clear and search the airport terminals, the FBI said in a statement Wednesday.
Nna Alpha Onuoha, 29, remained in custody on suspicion of making threats. No threats were found in authorities’ search of the terminals.
The airport is the nation’s third busiest one, according to its website. A request for comment from the airport was not immediately returned early Wednesday.
A search of Onuoha’s otherwise empty apartment found a note containing unspecified threats that cited Wednesday’s anniversary of the Sept. 11, 2001 attacks.
No harmful materials were found at the airport or the man’s apartment, the FBI said.
The Los Angeles Police Department Bomb Squad also inspected a package allegedly left at the federal Transportation Security Administration headquarters in the airport after he resigned, and the package was addressed to another agency employee, officials said.
The officers found no harmful contents in the package but found an eight-page letter in which Onuoha expressed disdain for the United States and referenced an event that led to a recent suspension, the FBI said. It was not clear Wednesday what the incident had been.
Later, a man authorities believed to be Onuoha made two phone calls to the TSA saying certain airport terminals should be evacuated.
