Hero security guard vaults over railing to save grandmother who fell down escalator in China

This is the heroic moment a security guard on patrol vaulted over a railing to aid a grandmother who fell down an escalator in China.

The quick-thinking officer named Li Yang was on duty at the subway station in Wuhan on September 11 when he heard a loud thud behind him. He swung around and saw that an elderly lady in her 60s had lost her balance and bashed the back of her head on the escalator steps.
