Chicago Tribune, 9/7/17:
No public alert issued after man is pushed onto Loop subway tracks
Ben Benedict stood near the edge of the Washington Street subway platform, waiting for a late-night train home, when he felt a hard jab to the back and tumbled to the tracks five feet below.
He stopped a foot short of the third rail and immediately looked down the tracks, but didn't see the train yet, according to Benedict. Then he looked up and saw the guy who pushed him. He was staring at Benedict and not saying a word.
SNIP
The attack happened more than a month ago but neither police nor the CTA have issued public alerts about it. . . .
