Ex-IIT Kanpur Professor GD Agrawal wrote three letters to PM Narendra Modi before his death on the 112th day of fast over Ganga. In his last letter, Agrawal wrote "Uma Bharti ji came to meet me. She made me speak to Nitin Gadkari ji...but response is expected from you". Agrawal alleged the government didn't do anything "fruitful" to save Ganga.
