Halloween me and a couple of mates went to a party. We were all really really drunk, I got was being stupid with some random boy and ended up slapping him but we sorted it out after I had apologised and it was done however hours after the police had arrived because two people got stabbed and instead of arresting anyone else I was arrested because of that boy. I've been on bail since then for ABH but the police said the boy has bruises on his face which is common assault not ABH. In the interview I didn't admit to anything, I said we had a little argument but i can't remember hitting anyone. They have asked me to go back to the station today I'm a little nervous as I'm a first time offender never had a problem with the police and never really had a fight before (I'm 17). What should I do about this/ what will happen to me?
