Camera reveals what caused woman to fall on subway tracks

ABC News released the shocking security footage from Metro Madrid that shows a woman walking along the subway platform texting, only to fall onto the subway tracks as the train turned the corner.

The incident took place on Oct. 24, and the woman is reportedly fine.

Onlookers watched in horror as the woman, seemingly absorbed in her phone and oblivious to where she was going, walked right off the edge of the platform. Bystanders quickly waved to the train conductor and helped the woman up.

Metro Madrid tweeted the clip and issued a warning about looking up from phones while maneuvering busy platforms.
