British national travelling to India on Indian passport.

Hi Guys, need help, in such a qunadry !!!!

Indian national, got naturalised 1st quarter of this year (hence out of the 3 month grace period) but never got around to surrendering Indian passport. I have to urgently travel to India on the 1st of Jan, 2015. Just realised that if were to surrender passport (3-5 working days) and apply for an Indian visa (3-5 working days) I would not be able to travel on the 1st . Hence was pondering plan b.

I know it is probably not the right thing to do, but I may have to travel on the Indian passport. My questions are as follows

I have read on the High Commission page that the penalty for travelling on an Indian passport after naturalisation is £145

1) Is there any way that immigration in India know that I have a British passport when I present my Indian passport (with valid UK visas) in immigration.
2) Do I have to pay the penalty of £145 at the airport??
3) Is it a lot of hassle? Would I find myself being eaten at by immigration sharks?
4) Are there any other issues I need to consider before I do this?

Any information will be greatly appreciated.

Kind regards

Dev
