Security staff at Los Angeles International Airport are being investigated after failing to pick up a handgun in an off-duty police woman’s carry-on luggage.
At LAX, one of the world’s busiest airports, the weapon went undetected during security screening and was only picked up after Officer Noell Grant realised she had it when she went to change planes in Taipei.
After informing local authorities, Ms Grant has been barred from leaving Taiwan as US federal officials attempt to resolve the matter.
US Transportation Security Administration worker Nico Melandez said authorities "determined standard procedures were not followed and a police officer did in fact pass through the (airport) checkpoint with a firearm”.
"We'll hold those responsible appropriately accountable.”
It is unclear whether Officer Grant is set to face disciplinary charges on her return to the US.
