"Nothing of concern" was found onboard the Southwest plane that diverted to Phoenix Sky Harbor Airport Monday afternoon, police said. Bomb-sniffing dogs and explosive experts with the FBI and Phoenix Police spent several hours searching the plane in response to a threat, but nothing suspicious was located.
Police investigators concluded the search about 8:15 p.m., about 4 hours after the plane was escorted down by two fighter jets from Davis-Monthan Air Force Base in Tucson. Traffic restrictions on the west side of the airport have since been lifted.
Southwest Flight 2675 left LAX at 2:12 p.m. Monday and was heading non-stop to Austin when it was diverted to Sky Harbor Airport.
Law enforcement officials in Los Angeles contacted Phoenix Police regarding the threat, and police and fire were there when the plane landed at Sky Harbor and parked in an isolated area. Passengers deplaned and boarded buses to be taken to a secure area for questioning.
Southwest Airlines worked to put the flight's 143 passengers on a later flight. They were scheduled to depart Phoenix about 10:10 p.m.
The threat was called in by telephone, according to the FBI.
"The FBI's investigation is on going at this time. All efforts are being made to identify the caller who initiated the bomb threat," said Manuel Johnson, spokesman for the FBI's Phoenix office.
Johnson added that the aircraft remains at Sky Harbor and that the TSA continues to screen luggage.
Roadways on the west side of the airport were restricted for about 4 hours Monday night. Up until 8:15 p.m., motorists were asked to enter and exit the airport only on the east side. Both directions are now open.
Flights in and out of Sky Harbor continued, but there were some flight delays. A Southwest spokesperson noted some flights were delayed due to their plane being grounded. As always, if you're flying or picking someone up, check flight status with the airline.
