Hi, I'm an ex police officer changing careers into teaching. It's just a thought, but were you given an official police caution, this would be you going into a police station and being read load of legal stuff and a police sgt being present? or was it a telling off from an officer? The first would be on your record the second only a local database. If it was the first I would definately declare it, but I doubt they will be that interested, perhaps be prepared for questions on integrity. Hope that helps..
