Noted environmentalist G D Agrawal, who is on "fast-unto-death" to press for cleaning up of river Ganga, was on Monday referred from BHU to AIIMS in New Delhi after his health deteriorated further.
Also known as Swami Gyanswaroop Anand, Agrawal was recently transferred to the Sir Sundal Lal Hospital of Benaras Hindu University from the district hospital after suffering a heart attack.
He was taken to New Delhi on an air ambulance from the Babatpur airport in Varanasi, sources close to Agrawal said.
Meanwhile, some of the close aides of Agrawal have alleged that he has been shifted unnecessarily and that in a vrecent letter sent to them, the activist had claimed to be in sound health.
Recently, Magsaysay award-winner 'Waterman' Rajendra Singh and two others had also quit from the National Ganga
River Basin Authority on March 10 expressing solidarity with Agrawal, who has been on fast for past 11 days.
