Will some action will be taken against me?

Sir.. Me and my friend was returning from gym my friend was driving and then his vehicle collided with another person and then they both started fighting my friend beat him and I was not part of that fighting I was just standing there like other 15 people present at the time. Then he filed up a case against my friend and police investigated but after 4 days in hospital he die and now I don't know how my name is also being involved in this scenario. Opposite party filed a case against my friend and one other guy whose name is not mentioned in FIR everyone out there saw that I didn't even touched that guy so why am being involved and will some action will be taken? I have to go jail? Police did came 2 times at my friends home but didn't came at my home? What consequences I have to face? Lifetime imprisonment or death sentence or fine for not doing anything? I don't have any evidence that I didn't touched him but those 15 people did saw that I didn't touched him. The guy who die, his wife who was not even present at that time filed up a case against my friend and other guy(me?) whose name is not mentioned in the FIR and she is saying that both of us had beaten his husband. Sir I don't know what i should do now please help me soon
