“Reports of a shooting Sunday morning at Harry Reid International Airport are unfounded,” the Las Vegas Metropolitan Police Department tweeted.
“The noise is believed to have been caused by an unruly subject,” police said. “That person is currently in custody.”
“A loud noise has caused panic at Harry Reid International Airport this morning, and created a security incident,” the airport, in Paradise, Nevada, said. “We appreciate the patience of those traveling today as operations are in the process of returning to normal.”
The airport alerted travelers to expect delays.
“Flights will be held as multiple concourses are cleared, and all passengers will need to be screened/re-screened at security checkpoints before boarding aircraft,” a follow-up tweet said.
