Staff and Wire reports
Authorities briefly evacuated a portion of Will Rogers World Airport after a security breach on Monday afternoon.
Passengers in the airport's post-security concourse area were evacuated about 3:45 p.m. Monday after Oklahoma City police officers found a bullet in the concourse, airport authorities said.
"They determined later that it was not a prohibited item," Airport spokeswoman Jennifer McCollum said. "All of the passengers were rescreened, however."
McCollum said four flights were delayed as 669 passengers filed back through security checkpoints.
"At no point at any time was anybody at any risk or any danger," she said.
