LOS ANGELES (AP) -- The chief of Los Angeles International Airport police says a lone shooter, that officials identified as 23-year-old Paul Ciancia, was armed with a semi-automatic weapon when he approached a TSA agent Friday morning and began shooting.
An official with the government employee's union confirmed that TSA agent was killed
Police say the suspect, who was apparently injured following an exchange of gunfire with officers, is in custody.
Police say two other people besides the TSA agent were hurt.
The airport shooting sent travelers scrambling for safety. Some who had already cleared security rushed onto the tarmac, while others were locked down in restaurants and lounges.
Air traffic controllers reported seeing passengers spilling from the terminal onto the tarmac, "getting out as fast as they could," according to one controller.
One witness says he heard "about a dozen gunshots" from inside a security gate at the terminal.
Thousands of fliers are delayed after the shooting closed parts of the airport for hours.
Flights heading for LAX, which had not yet taken off, were held at their gates by the Federal Aviation Administration.
Others in the air were diverted to other airports. Travelers hoping to fly out were unable to reach Los Angeles airport because of road closures.
