Lucknow's traffic police but a wrong challan out of spite.

Hello Everyone, I am based out of Lucknow, recently while driving my car I entered a one way traffic zone from opposite direction. I was following google maps and apparently it guided me to take a wrong turn which was a no entry (near Hazratganj main chowk), though I was little sceptical about the turn at first since most of the traffic was avoiding it but there was no signate/marking so I took the turn. Traffic police was waiting just around the corner, he clicked photo of the vehicle and demanded Rs 1000/- as bribe. Since I knew fine for wrong side driving is Rs 500 I asked him to give me a challan. Now, when I got the challan it says "Disobedience of Authority" and have put a fine of Rs 2000/- . What should I do now? 1. Should I challenge this in virtual court? If yes, then how is it done and would it be of any use.
