She is believed to have been abducted around 8:15 a.m., according to the Amber Alert

She is approximately five-feet-tall with black hair, brown eyes and weighs 90 pounds, according to the post. She had on a white T-shirt, blue jeans and black jacket before she disappeared, police said.

The girl split up from her group before checking in at the airport, police said. She was reported missing going through departures, a Metropolitan Washington Airport Authority Police official said during a news conference.

“She met up with an unknown, Asian female, who assisted the 12-year-old with changing clothes,” the Facebook post said. “The two then walked together to the ‘Arrivals’ area of the airport, eventually disappearing from the camera view.”

Upon leaving the airport, the girl was seen entering a white Infiniti vehicle with New York tags, the official said, adding that she is considered to be "in extreme danger" due to her age.

The suspected abductor is believed to be a middle-aged woman with black hair and a black dress on, police said. She was initially said to be in her 40s, however authorities later described her as being in her 50s.

The woman was observed entering the airport with a male who was believed to be driving the vehicle, the police official said. The girl reportedly did not leave the building by force.

Anyone with details are advised to call 911 or the Metro Washington Airport Authority Police at (703) 417-2400.
