A dangerous prank sent a San Francisco cab driver to the hospital Friday morning.
Police said the cab had passed through the Broadway tunnel near Larkin Street when a brick crashed through the windshield.
Police think someone was standing on the overpass on the Hyde Street side and dropped the brick onto the cab, which left a hole in the windshield.
There's no word on whether the person who dropped the brick has been caught.
The cab driver was taken to a hospital with minor injuries.
