I met with an accident today wherein the car in front of me hit a person and that person collided with my car. The car in front of me ran away. since it was getting dark and the car in front of me speeded I could not note the car number. I stopped the car instantly and called police who also sent the person to hospital. The person had suffered some injuries and was bleeding. The police took a note of my contact details and asked me to go. After that they called me to come later for giving statement. Do i need to worry for anything or should I have done anything in addition.
