What do u think will happen??

Right, i got arrested in May and was kept in a cell for 13 hours...there trying to get me done for ault occasioning actual bodily harm, but i actually didnt do anything wrong apart from to try and stop a fight between these 2 gangs of guys ( its a long story ) some of the guys had to go hospital with their injuries. But anyway i ended up getting blood on my trousers which hasnt helped the cirstance. Im currently on bail and have to go back next week to see what there going to do. I really cant be doing with a criminal record and i cant get another caution.
