LOS ANGELES – Security measures were apparently not followed after an off-duty Santa Monica police officer was allowed to board a flight to Taiwan at Los Angeles International Airport (LAX) with a handgun in her carry-on bag, authorities said Thursday.

Santa Monica police officials were notified last week that Officer Noell Grant was not allowed to leave Taiwan. According to authorities, she entered the country on April 13 in possession of a firearm.

Grant was reportedly detained while on vacation with her family during a layover to Thailand, reported CBSLA.

A Transportation Security Administration (TSA) spokesperson told CBSLA: “TSA has determined standard procedures were not followed and a police officer did in fact pass through the checkpoint with a firearm. TSA expects every employee to follow procedures and holds its workforce appropriately accountable.”

Santa Monica police spokesman Lt. Saul Rodriguez told the Daily News the gun was a “personal, off-duty” firearm and not a service weapon.

It was unclear whether Grant has been charged with a crime in Taiwan.
