The FBI on Tuesday continued to investigate a security threat that forced the evacuation of more than 170 passengers from an American Airlines commercial plane traveling from Charlotte to Minneapolis Monday night.
The plane, a twin-jet Airbus A321, took off from Charlotte Douglas International Airport at 8:43 p.m., then returned at 9:07 p.m., according to FlightAware, an online tracker of flight departures and arrivals.
Charlotte-Mecklenburg police evacuated the passengers, an American Airlines spokesperson said.
The airline switched out the aircraft, and the passengers departed for Minneapolis-St. Paul about 12:30 a.m., American Airlines spokeswoman Katie Cody said.
Citing the ongoing investigation, FBI spokeswoman Shelley Lynch declined to identify the threat that caused the plane to return to Charlotte or say whether the FBI has taken anyone into custody.
