Police verification for govt job

I have been fined by a railway court,of a remote location, now should I mention this in the bio data form for govt job where it is asked if convicted/fined/arrested by any court of law. If I am going to mention it I'm sure I won't get selected and if I don't mention there's a chance I could get my dream job, so please tell me what should I do. Should I take the risk , what are the chances of getting caught in the police verification. Please answer as soon as possible.
