The Hazare Team said the Gandhian was on fast and was not even taking water after he was taken to a police facility in north Delhi.
"He is on fast. He is not even taking water," a spokesperson for the Hazare Team said.
Hazare was detained from an apartment in east Delhi's Mayur Vihar this morning after police failed to persuade him to call off his plans to defy prohibitory orders and stage a protest at Jai Prakash Narain Park here.
Besides Hazare, his close associates Arvind Kejriwal, Kiran Bedi and Shanti Bhushan were also detained.
The Gandhian had announced that he would launch his indefinite fast from today demanding withdrawal of the "weak" Lokpal Bill and introduce a strong legislation to fight corruption.
