Hazare, who arrived here this morning from Dhule town as part of his state-wide tour for strong Lokayukta Bill, has been taken to Saibaba Heart Institute and Research Centre, where he is being examined by doctors, hospital sources said.
"Hazare cancelled his Nandurbar district tour due to fatigue and weakness," P B Karanjkar, president of the Nashik unit of Bhratachar Virodhi Andolan said.
He, however, said that there was nothing serious about Hazare's health and added that the Gandhian is scheduled to address a public meeting here tomorrow evening.
Hazare has been on a month-long tour of the state on the Lokayukta Bill issue from May 1.
In January, Hazare had been hospitalised for a week, which had forced him to call off his tour of five-poll-bound states.
