On Sunday morning, a "loud noise" led to erroneous claims of an active shooter at Harry Reid International Airport, prompting flight delays and cancellations.

There was no shooter, merely a loud commotion in Terminal 1 produced by someone being detained by police.

At the Las Vegas airport, 53 flights have been cancelled and 322 have been delayed.

The loud noise caused  panic at Harry Reid International Airport.

The loud noise made by a "unruly individual" who is currently in custody.

During the panic induced by the boom, some people rushed through security checkpoints.

Flights were suspended as the terminal was shut down and cleared.

Delays are expected to continue throughout the day, according to the airport.

There were no reported injuries.
