I am not sure about India, but I know what would happen in my birth country: they would bring you to the interrogation room and say, "You can pay us a 'fine' on the spot or we will arrest you and you will miss your flight." Sure, you can request a consular assistance, but you would miss your flight anyway and lose $$ on new tickets. Also, since you used this country's passport to enter the country, the US consular officials may not even do anything to help you. So, anyone in the right mind would just pay this unofficial fine and be done with it. From what I have heard from my Indian colleagues, I assume this situation is possible in India too. Am I wrong?However, I am thinking what will be the next step? Once they arrest you, you call the state government (or consulate) - get representation and then ... will they deport you back to US / Australia? Interesting line of thought...
