SAN DIEGO -- A San Diego woman who was showering in her second-floor apartment has been injured after she fell through a window and into a 15-foot light shaft.

U-T San Diego reports the woman suffered unspecified injuries early Tuesday and was taken to a hospital.

Authorities say the woman was showering, lost her balance and fell through an open window, measuring 2 feet by 3 feet, into the shaft.

The woman landed at the bottom of the shaft and firefighters rescued her by lifting her into a first-floor apartment window.

Battalion Chief David Connor says it was "an odd or freakish type of accident."

Each apartment has a bathroom window into a shaft that is designed to bring light from the rooftop to interior rooms.
