LOS ANGELES (AP) -- A Los Angeles International Airport security screener has been charged with making threats hours after he quit his job that led to the closure of some terminals.

Court records show 29-year-old Nna Alpha Onuoha was charged Wednesday with one count each of making a false threat and making threats affecting interstate commerce.

If convicted of both counts, he could face up to 15 years in prison.

Federal officials say Onuoha made two calls to LAX after resigning and told officials to evacuate terminals. Parts of the airport were cleared and searched. Nothing was found.

A website has a picture of Onuoha and rambling letters attributed to him that promise something more devastating than the 9/11 attacks.
