Hi Kev. I did a similar thing a while back. I kicked a tram inspector in the ribs, It turned out I had cracked his ribs, he then left his job bcause of the stress. I was initially just given a warning. The reason I kicked him was bcause he grabbed hold of me and tried to restrain me, 2 wks later I got into a similar incident wherby I smashed my hand through a pub window after an argument. I was arrested, took back to court, It was adjourned for character reports, and I was then later bound over for 12 months to the tune of �50. Bcause you have been in trouble previously this will go against you, however, my suggestion would be to say that you were acting in self defence and that whilst in the toilet or somwhere cctv less, he had pushed you into the door or on the floor etc,, self defence covers a mutitude of sins. In relation to fines etc, it wasn;t intentional that he broke his ankle so I would say that you may get bound over or a community order.
