The CBI has registered a case of alleged violation of the Foreign Contribution (Regulation) Act against human rights activist Harsh Mander and his NGO and searched his premises on Friday, officials said.

The Home Ministry had stated that Section 3 of the FCRA prohibits acceptance of foreign contribution by correspondents, columnists, cartoonists, editor, owner, printer, publisher of a registered newspaper but Mander has been writing columns and articles in newspapers and web portals.
