A person came in front of car and died

My friend was driving his father's car, suddenly one men fall-down in the road in front of his car and my friend don't have that much time to hit the break and save that men, this incident happened in just 2 second. So that men was suddenly fall-down in front of his car and met an accident. That men was dead at that time on accident spot. After that my friend call the nearest police and tell them what is actually happened. Now i want to ask you that what is the legal sections are apply on my friend?? My second question is that is this "hit and run" case ?? because the opposition lawyer put this case as hit and run case. My friend was not run away from accident spot after the accident.So what to do in that case ??
