A Southwest Airlines flight scheduled to leave Louisville, Kentucky, on Wednesday morning was evacuated on the runway after a passenger’s Samsung cellphone caught fire, passengers and the airline said.

Southwest said in a statement that passengers and airline employees were taken off Flight 994, which was scheduled to leave for Baltimore, after a customer reported “smoke emitting from a Samsung electronic device.”

The Verge identified the passenger as Brian Green and his phone as “a replacement Galaxy Note 7.”

A Samsung spokeswoman said in a statement Wednesday that the company was unable to immediately confirm which device was involved in the episode.

“We are working with the authorities and Southwest now to recover the device and confirm the cause,” the statement said. “Once we have examined the device, we will have more information to share.”

The company, which is the world’s largest smartphone maker, announced last month that it would replace 2.5 million of the smartphone model because of a flaw in the battery’s cell that could result in the devices bursting into flames or exploding.

Green told The Verge that he had picked up the new phone on Sept. 21, after the recall. The episode could be damaging for the company, since the replacement devices were thought to be safe. The new models had been approved by the U.S. Consumer Product Safety Division.

Christine Sundman, 65, a retired teacher who was planning to return home to New Hampshire after visiting her daughter’s family in Louisville, was one of the passengers evacuated from the flight. She said a woman sitting near the phone’s owner had told her that the device had just been powered down when it caught fire.

The owner quickly dropped the device on the floor, Sundman said in a phone interview.
