In the two-minute clip, shared on Live Leak, police can be seen examining the interior of the car and pushing buttons on the dash board in the hope of opening the boot.
Eventually they succeed and help the captive to safety, removing a cloth from around her mouth and using a knife to slice through ties around her wrists.
It is not yet known where exactly the footage was captured and the identity of the victim and her captors is not yet known.
At the end of the video, the relieved and emotional woman throws her arms around one of the officers.
