Running onto a pitch during a english premier league match. I am 16 years old and i'm from Ireland.

I am a huge arsenal fan and I am going to their next home game. I want to run onto the pitch during the match and I want to know what consequences would be given to me. I know that you can be put in front of a judge and then you can be fined and sometimes worse can happen but I am only 16 so what would happen to me ? would the same rules apply ? I read about a guy who ran onto a pitch during a tottenham hotspur game and kicked the ball during a free kick but I wouldn't kick the ball and I would wait for the ball to go off the pitch or for the game to be stopped at a certain point and then I would run on to the pitch and then run back off so I want to know what could happen to me for doing this.
