The driver said he met an acquaintance in the market and chatted for a while but did not notice the boy when he started the car. He felt he hit something and got out to check, only to find a boy lying under the right wheel, bleeding.
"I was stunned at the time and thought nothing, I quivered all over," Gao said, adding that he did not leave but went to call his boss to ask what to do.
"I do want to do something for the boy, but I had no idea what I should do, and I feared his parents would come and hit me, so I stood there. If my mind was as clear as it is now, I would have sent the child to hospital immediately," Gao said.
