NORTON, Mass. (WHDH) -- A car caught fire and the driver was trapped inside, but the woman is alive thanks to a police officer who rushed to her rescue.

The 911 calls poured in as smoke filled the car.

Dispatcher: 911, this line is recorded. What is your emergency?

Caller: I think someone um, in a car, went straight into the woods across the street from my house.

Caller 2: There’s a car involved in the woods and there’s smoke and then like it’s almost on fire.

Caller: I just called; the car is on fire now in the woods.

A Norton police officer was first on the scene. He knew the situation was bad.

“When the officer arrived he noticed that the vehicle on fire. The operator, the female operator, couldn’t get out of the vehicle due to some severe leg injuries,” said Lt. Todd Jackson of the Norton Police Department.

“Heavy fire in the engine department up to and past the windshield, just as we were pulling up it was breaking through the dash area which we refer to as the fire wall,” said Capt. Kent Campbell of the Norton Fire Department.

Norton fire crews were raced there, but before they arrived they heard over the radio a police officer catching his breath after bravely pulling the teen out the window.

Radio Transmission: “Female operator, multiple contusions, I extracted her from the vehicle.”

“As soon as she was out of the vehicle, probably within a minute, the passenger compartment was fully engulfed,” said Jackson.

Crews rushed the young lady to the hospital.

“It spread so fast. She wouldn’t of had much of a chance if it wasn’t for him,” said Campbell.

The woman is expected to be okay. She isn’t facing any citations, but police continue to investigate how the driver hit the tree. Officials said alcohol does not appear to be a factor.
