You didn't read the article. She landed on North Sentinel island and interacted with the Sentinelese. Then, later in the article it focuses on Jarawa.

I did read it. I just don't trust the veracity of the claims.

The best I can find is this book: https://books.google.com/books?id=-4PDCQAAQBAJ&pg=PA140&lpg=...

This text claims to have made friendly contact in 1986, and says 1994 had contact on the eastern coast.

These dates don't line up with the story, and I can't find any official source information about the contact, so the inconsistency is a red flag.

She apparently wrote a book 15 years ago: http://www.amazon.in/Tribes-Car-Nicobar-Madhumala-Chattopadh...

I don't know how one would go about researching Indian anthropological expeditions to find the officially-documented connection to reality, but presumably that's where you'd start, if you wanted to verify the story.
