A driver who was on the scene shortly after the first accident happened has told how she talked to the 21-year-old woman.
The witness, who did not want to be named, said although she didn't see the accident, she was right behind it and was on the scene before paramedics and police arrived.
She said: "We saw four of the five people crawl out of the car - they were very distressed. I went to the aid of the girl trapped in the car, I held her hand and was trying to keep her talking. It was pretty scary."
The witness also said that she didn't see PC Pratt get hit by the car - but saw him in the road afterwards. "We went past the scene as we were moved on - it was not a nice sight to see," she said.
