Days after Ganga activist G D Agarwal passed away, Congress president Rahul Gandhi Sunday expressed concern over the deteriorating health of another person fasting for the conservation of the river.

Sant Gopaldas, 36, has been fasting for the cause for over 110 days. He began his fast against mining in the Ganga river bed first in Badrinath and had been fasting at Triveni and Bag ghats of the Ganga in Rishikesh since June 24.
