"He has fever, let us request him to stop his fast. Anna can continue his dharna," Bedi said addressing supporters at the MMRDA ground where Hazare was sitting on fast.
The 74-year-old activist was suffering from viral infection and his personal assistant Suresh Pathare had been insisting that Hazare was well and he will be sitting on fast.
"Anna is unwell. Will you request Anna to withdraw his fast?" Bedi asked the crowd, which responded with a loud "Yes".
However, Hazare, looking quite under the weather, waved his hand in a gesture of "No".
Kejriwal and another close aide Manish Sisodia also requested Hazare to end his fast.
Hazare, who has been suffering from cold and mild fever for the past three days, reached the grounds at around 12.30 pm after a rally from the guest house where he was staying to the ground which took over two-and-half hours.
"He is a little weak as of now, but will be fit to fast from tomorrow. His blood pressure and other vital parameters are normal. He has got a little cough and cold but he is getting better," his doctor D G Pote had said on Monday.
The activist has been under medication for the past three days, he said.
