The incident took place at the U Street / African-Amer Civil War Memorial / Cardozo station on April 21.

A 54-year-old man drove his motorized wheelchair onto the tracks. After he fell, his wheelchair landed on top of him.

The man was not in imminent danger of being struck by a train – the nearest train was 3 stops away, but the danger was from the electrified third rail, according to a Metro spokesman.

Two men jumped off the platform and rescued him from the tracks.

He had his mouth bloodied from the fall, but no other visible injuries, and was later sent to the hospital.

It is unknown at this time what caused the man to go over the edge of the platform.

None of the individuals involved have been identified.

The fall and the rescue were captured by a Metro surveillance camera.
