RICHMOND, Va. -- Richmond International Airport was evacuated Tuesday morning after it received a threatening phone call, a spokesman said.

Sweeps of the airport’s terminals and parking decks did not find anything, the airport said in postings on Twitter. The terminals reopened to passengers and airport workers about three hours after the call was received shortly after 6 a.m.

Sgt. Police Sgt. Thomas Molnar said the call was deemed serious enough to evacuate the terminals.

Most flights were held while the airport was checked. Five flights were permitted to land, although they were to be held short of the terminal, Molnar said.

Katie Schexnayder, 24, of Richmond arrived at the airport Tuesday morning to catch an 8 a.m. flight to Nashville, Tenn., only to be told shortly thereafter that the terminal had been evacuated because of a bomb threat. She said passengers were evacuated around 6:30 a.m.

Passengers waited outside, roughly a quarter-mile from the terminal, Schexnayder told The Associated Press in a phone interview from the airport.

“Not far away enough I don’t think, but that’s just me,” she said.

She said the mood was calm and that officials were friendly and willing to answer questions.

“They’re nice enough, just telling us they’re clearing this, clearing that,” Schexnayder said when asked how airport officials were handling the situation. “They’ve been good and keeping us informed enough.”

Molnar said the Federal Aviation Administration has been notified.
