Aggravated Batterys

Making the long story short, basically it was a bar fight that happened and 3 of my friends were the victims. They were waiting outside for me and then later someone comes up to me and says "I think your friends are fighting outside" and so I went outside to see what was going on. But, you couldn't tell who was who cause there were so many people outside. So finally I found my friends with riped shirts and etc.. But since they were so pumped they didn't pay attention to me and so I went up to the other people and asked what was going on, later another male starts to curse at me so we had verbal arguement and then I ran after him but then I tripped on something and fell.While I was trying to get up someone started to hit and pull my hair and etc... I couldn't really see who but then later after the whole incident cops came and didn't arrest anyone and checked everyone out physically and nothing. 2 months later a felony warrant came out for my arrest for aggravated battery so I turned myself in and found out that the person that was hitting me broke something in the hand and pressed charges against me. Is that possible? I think thats unfair and plus they had more people and I didn't even physically touch anyone.What are my odds? - Is this your question? Add additional information
