A passenger’s weapon accidentally discharged at the Atlanta airport

 (CNN) — The accidental discharge of a passenger’s weapon in a security area of Hartsfield-Jackson Atlanta International Airport caused widespread panic Saturday afternoon, prompting a brief halt of departing flights over the busy travel weekend.

Three people suffered non-life-threatening injuries, the Transportation Security Administration said in a statement. It wasn’t immediately clear what caused those injuries. Atlanta police had previously said no injuries were reported.

The incident began when a “prohibited item” was identified going through the X-ray at the security checkpoint, the TSA said. A bag search was initiated, and a TSA officer told the passenger not to touch the property. However, as the officer searched the bag, the “passenger lunged into the bag and grabbed a firearm, at which point it discharged,” the TSA said.

“The passenger then fled the area, running out of the airport exit,” the statement said, adding, “This was not an active shooter event.”

Airports spokesperson Andrew Gobeil characterized the discharge as accidental and said the loud noise created a “sense of chaos.”

Airport officials and Atlanta Police know who the individual is, Gobeil told CNN’s Jim Acosta, because the incident occurred while the passenger was being screened.

Erika Zeidler, who was traveling from Atlanta to Anchorage, Alaska, said she was sitting in a restaurant in Concourse T when people began running down the hallway.

“We thought they were late for a flight, and then more and more people started running,” she told Acosta. “There was some screaming and then somebody stopped and said, ‘There’s a shooter, you need to go.'”

An investigation into the incident remains ongoing, Gobeil said.

In the meantime, there is no danger to passengers or employees, airport officials said on Twitter. Officials gave an “all-clear,” and the airport was resuming normal operations.

A ground stop was called for the airport for all departing flights, per the Federal Aviation Administration, but was soon lifted.

Details about the weapon or circumstances surrounding the accidental discharge have not been made available.

The FBI and the ATF are “providing investigative assistance” to the Atlanta police, according to a spokesperson for the ATF. The White House is also “monitoring” the incident, a White House official said, referring questions to local law enforcement.

The shooting scare comes as the Thanksgiving travel period is getting underway. On Friday, the Transportation Security Administration screened more than 2.2 million airport travelers across the country — the highest checkpoint volume for a single day since the pandemic began, according to a TSA spokesperson.

TSA Administrator David Pekoske recently told CNN that airline passengers bringing guns to the airport is a “huge problem.” Last month, the agency reported catching 4,650 firearms — a majority of them loaded — at security checkpoints in the first ten months of 2021. That number surpassed the full-year record of 4,432, set in 2019.

Witnesses recount chaos after scare

Witnesses described confusion and disarray as panic erupted in one of the world’s busiest airports.

Zeidler and others took shelter in a TGI Fridays restaurant, she said. Photos she shared on Twitter showed a crowd of people standing on the tarmac beneath a jetway as the incident unfolded.

Video posted on Twitter by Haşmet Asilkan showed people running out of the airport, telling others of a shooting that had taken place inside.

Greg Romero had just gotten off a flight from Salt Lake City when he heard there was an emergency, he told CNN’s Fredricka Whitfield. Airport personnel “shut off all the escalators and cut off all passengers and turned off the tram,” said Romero, the father-in-law of CNN correspondent Nadia Romero.

“Right now airport personnel is doing a really good job keeping everybody calm,” he added.

A few travelers were “a little bit panicked but more frustrated,” Romero said. “They’re trying to catch flights, to get out of the airport. For the most part, people are just lined up against the walls.”

Dianne Callahan was traveling with her son and had just boarded her flight to New York when the crew closed the door to the plane. That’s when she said she heard screams outside the plane. She also heard sirens, Callahan said, but didn’t know what was going on.

“It was an extremely tense situation,” she said. “People were pushing to get on the plane that were not even on our flight. That’s how scared they were.”

Callahan and her son were then sent to go back through security, she said.

In response to the incident, Delta Airlines, which is headquartered in Atlanta, announced it was issuing a travel waiver to assist impacted customers.

“With this, the fare difference for customers will be waived when rebooked travel occurs on or before Nov. 23, 2021, in the same cabin of service as originally booked,” the statement said.

“Delta is coordinating with TSA and Atlanta airport officials to accommodate customers as quickly and safely as possible,” the airline said. “We are also working to proactively accommodate customers who may have missed a flight.”
