Operations at Los Angeles International Airport returned to normal Saturday morning after a false alarm caused panic at the facility hours earlier, authorities said.
The chain of events started Friday night around 7:30pm when a woman driving on the lower level of Terminal 5 had a medical emergency, causing her to lose control of her car, according to a press release from LAX spokeswoman Nancy Castles.
The woman hit several other cars, causing a loud noise. The sound of the crash prompted a false report of shots fired and a separate report of a man with a gun, according to Castles.
When Airport Police officers responded, no threat was found, officials said.
But LAX was once again thrown into panic and air travel was disrupted.
About 4600 passengers were affected, and 60 flights on Delta and American Airlines were delayed, according to a statement from the airport.
The incident happened exactly three weeks after a gunman went on a fatal shooting rampage at LAX.
TSA security officer Gerardo Hernandez was killed in the Nov. 1 rampage.
The alleged shooter, Paul Anthony Ciancia, was charged with murder of a federal officer, and commission of violence at an international airport.
