"I was standing talking with a woman when I heard a commotion, and I looked across and saw six young men on scooters," she said. "At first, I thought one of them was being set upon by three others. I was not going to stand by and watch somebody take a beating or worse, so I tried to intervene."
She added: "What concerned me was that too many people just stood around watching as if they were in shock, and nobody was doing anything. When I got closer to them, I realized it was a robbery, and then I was even more angry that they felt they could get away with what they were doing in broad daylight."
