SAN FRANCISCO, Jan. 11 (UPI) -- A witness to the "chaos" caused by a broken escalator at a San Francisco subway station captured video of commuters escaping by shimmying up the hand rail.
Charlie K. Perkins posted a video to Twitter showing the scene Monday at San Francisco's 24th Street station, where an escalator undergoing maintenance was preventing people from leaving.
Perkins said the maintenance work left the escalator's stairs area as an "open dangerous pit."
The video shows commuters climbing -- and in some cases, shimmying -- up the escalator's hand railing to escape the "chaos."
"People are desperately trying to get out," Perkins wrote.
