Chennai Airport — do not buy from chennai airport duty free i[censored] have a domestic transfer

I am writing this complaint because of the harassment i faced in chennai airport today. I have bought liquor from duty free and it was sealed and in pristine condition with all receipt with me. Due to poor infrastructure of the airport i have to go out of international arrival and walk along the road and enter the domestic terminal for my connecting flight back to kolkata. After checking my luggage in... When i went for security check.. To my utter disbelief the cisf personnel refused to let the liquor bottles that i have bought from the duty free to take on board though they were sealed and packed buy the duty free shop because i have entered the terminal from outside (When there is no option of domestic transfer through the inside of the airport). They insisted on putting it in check in baggage inspite of repeatedly telling them that i have already checked in my luggage and don't have any suitcase with me. Mr anand prakash was in charge of the security here and it's impossible to talk sense with him. Poor infrastructure of the airport combined with incompetent staff and security makes the experience a nightmare for travellers. What's the point of having a duty free shop i[censored] cant carry the products in the hand luggage. I had to take out my camera with the lenses and my laptop and other stuff... Just to put the bottles in the backpack and put it in check in baggage again and carry the contents of my backpack in hand. Never have i faced such problems in any other indian airport during a domestic transfer. They r so concerned with bottles that they don't even realise that people are taking lighters and matches with them on board. This is the state of security in chennai airport which is nothing but an eyewash and harassment for travellers. Avoid chennai airport if with want to shop in duty free. This is my ernest request to the concerned authorities to look into the matter and take necessary steps so that other travellers don't have to face such harassment in future.
