You are unclear on what you are expecting in the post. If its a breach of the peace, nothing will happen. If you were arrested it was to end an, or prevent the reoccurence of a breach of the peace. You would have been charged to appear at court, usually the next available slot, where you would have been given a bind over. If you werent arrested, then you would have been informed if you were bein reported for summons, and for what offence. Without the right information, cant offer you anymore information. As for the IPCC, they wont help you, its not serious enough. If you are really dissatisfied, make a complaint at your local police station, in reality though, the outcome will be minimal .
