Authorities in China have released remarkable video taken last month of a teenager falling through a sidewalk.
The unsuspecting girl was caught on surveillance tape stepping and falling through the pavement while walking down a street in northern China.
A passing cab driver stopped immediately and climbed into the 20 foot deep pit to help the girl.
Eventually firefighters were able to pull both out.
Officials say water eroded the ground under the sidewalk causing it to become unstable.
