Can Government withdraw Bharat Ratna awarded?

An unbelievable statement appeared in The Print newspaper. The Print carried out excerpt from a book titled "Ä Rude Life" by Vir Sanghvi.

I will reproduce the portion from the excerpt:

What none of us realized was that the sanyasi had gathered up every secret file he could get his hands on at the PMO before they booted him out. He had a treasure trove of confidential communications, government files and secret letters, all kept safely, perhaps in those Air India attaché cases.

The heading of the excerpt in the Print was titled as "Morarji Desai had stolen PMO documents. Was set to reveal classified secrets"

If the above statement is true :

• Can / Will Government of India withdraw the Bharat Ratna awarded (1991)?
• Will Government of India set up a committee to know which documents were stolen and initiate process for retrieval of the stolen documents?
