A person was in custody after a disturbance at Harry Reid International Airport in Las Vegas on Sunday morning sparked panic among travelers, false reports of an active shooter and ongoing delays and cancellations, airport officials and Las Vegas police said.
The panic was sparked by what an airport spokesperson called a "loud noise" that created a "security incident."
Las Vegas police said on Twitter that the disturbance was believed to have been caused by an "unruly subject" who has been taken into custody.
Videos posted to social media show passengers running through the airport and screaming.
A spokesperson for the airport said the panic led some travelers to rush through security checkpoints without being screened. They then had to return to the checkpoints to be re-screened, leading to delays.
An airport spokesperson tweeted Sunday afternoon that delays were expected to continue and that cancellations were possible and urged passengers to check the status of their flights with their airlines before they go to the airport.
The airport had 52 canceled flights and 210 others had been delayed as of Sunday afternoon, according to the flight tracking platform FlightAware.
