Well the real answer was provided by the gang.
I asked them why they remained around my car, as though guarding me and my vehicle. They said they are actually criminals. But they knew that the place is very dangerous for a woman to be alone in a car. Hence they thought of guarding me. When they saw the hospital vehicle arriving, they left.
They were human beings looking after another human being. A simple act of kindness. Nothing divine happened. Which explained why others have been attacked in a similar situation. They did not find themsleves with humans who looked after other humans.
Strange she should read so much into it. But then people 'want' to believe.
