Social activist Anna Hazare on Saturday termed as "ironic" the arrest of Delhi Chief Minister Arvind Kejriwal, who was part of the Jan Lokpal movement, in a corruption case even as he demanded a thorough probe into the matter and punishment for the guilty.

Anna Hazare in a statement accused Kejriwal of betraying the trust of crores of countrymen and rued that political ambitions destroyed the 2011 anti-corruption movement.
