Yoga guru Ramdev and the Art of Living Foundation head Sri Sri Ravishankar today joined protestors, expressing solidarity with Anna Hazare outside Tihar Jail.
Ramdev, with whom Hazare and his associates have differences due to his alleged links with Hindutva elements, reached Tihar Jail this afternoon.
Earlier, Ramdev submitted a memorandum against Hazare's arrest to President Pratibha Patil.
Addressing protesters, Ramdev termed Hazare's arrest as a "conspiracy in the name of democracy".
"Anna is fighting for a strong Lokpal and his dream will be fulfilled. The whole country and all patriotic countrymen are with him in this struggle," he said.
Activists Kiran Bedi, Swami Agnivesh and Medha Patkar had earlier joined hundreds of protestors while a large number of the Gandhian's supporters took out marches across the city.
