Fined by court of law???

In 2005, I was taken to police station for drunkenness and nusiance in public. There after my medical was done and I was let to go on surity of bike papers. They called it bail in bail out. After one month I got a call from court to pay a fine of Rs 1000. Now I have to fill a form in which i got to mention whether in my past I have been convicted / fined by court of law / arrested. there wasn't any trail. I wasn't questioned, What kind of case is this.I even never appeared in court.
