DCist first reported a version of this story. Here's another, along with pics.
At about 8:30 a.m. April 6, at the corner of 3rd and E streets NW, a woman attempted to board bus # 2389 on the D-6 route with a pit bull, apparently claiming it was a service animal.Other items:
The dog had a harness and a red vest, but the woman could produce no papers.
When the bus driver refused to allow the woman and dog to board, she and her dog stood in front of the bus, refusing to move.
The bus driver then moved the bus forward attempting to push the woman and dog out of the way!
Metro and DC police were called to the scene, and the bus was off loaded. An ambulance was called, but it was not clear if the woman was injured.
