TEMPLE CITY (KTLA) -- A Temple City woman is in federal custody on charges that she called in a fake terrorist threat on a flight that her ex-boyfriend was about to board at LAX.

Police say 45-year-old Lizet Sariol was looking for revenge on the man, after he "unfriended" her on Facebook.

She is accused of making an anonymous call on Sept. 25 to a customer service representative at United Airlines naming 5 French travelers, including her ex-boyfriend, as a threat to a flight they were scheduled to board that day.

According to FBI spokeswoman Laura Eimiller, Sariol told the representative that she received a suspicious text message from one of the men and was also intending to notify officials at LAX.

The travelers were questioned by FBI investigators upon arrival and indicated that one of them became romantically involved with Sariol during their 3-month vacation in the U.S. The man told investigators he believed Sariol may have filed the complaint because she was unhappy over the ending of the relationship.

Investigators found that Sariol had sent threatening texts and Facebook messages to some of the men, including one saying she would ensure the men would be arrested.

"Already called the airlines considered you all terrorists including annie," the text read.

She later admitted to investigators that her call was made "in anger" and was "meant to sound suspicious."

Sariol has been charged with providing false and misleading information and fabricating a terrorist threat.

If convicted, Sariol faces 5 years in federal prison.
