See National copy NNBLIND: A blind former doctor has strapped a camera to his GUIDE DOG to capture the abuse he gets from commuters during rush hour. Amit Patel, who lost his sight three years ago, says he is constantly barged and pushed out of the way as he navigates around the trains and buses of London. The 37-year-old says other travellers step over guide dog Kika and even hit her with umbrellas to get her to move out of the way on escalators.
