A small plane crashed in a desert field near I-17 and the Carefree Highway Tuesday morning.

Phoenix Fire Department officials said firefighters treated and took three people, who were able to walk from the plane, to the hospital.

Phoenix Fire said the three adults had minor injuries and there was no fire associated with the plane crash.

It's not clear yet where the plane took off from, where it was heading or what caused the plane to go down.

The investigation is ongoing.
